Q: One sign that a guy may like you is if he reacts to your posts on social media. He might do more than just "like" your updates. For example, he might comment on your posts or reply to things you upload, or he even may send you direct messages on social platforms.  Look to see if he comments on other people’s posts as well. If he comments frequently, this may just reveal that he is an avid social media user. However, if he rarely “likes” or comments on other posts, this is a sign that he might have feelings for you. After he publicly comments on one of your photos or posts, respond to him. If he is eager to start up a conversation with you this way, it may reveal that he likes you or at the very least enjoys messaging with you.  For example, he may say "That is a great photo! Where are you?" You could respond by saying "I was in Vancouver last week. Such a beautiful city! Have you been?" If a guy you just met starts "liking" or commenting on old photos of you, this is a sign that he is interested. It means that he has spent time looking back through your old photos probably because he wants to know you better or he just enjoys looking at pictures of you! When a guy likes you, he will want to connect with you and follow you on a variety of different social media platforms. For example, he may add you to Facebook and Snapchat, and start following you on Twitter and Instagram. Adding you to a number of social media sites is likely a sign that he wants to look through your posts, photos, and selfies in an attempt to get to know you better.
A: See if he interacts with your posts. Reply to his comments. Notice if he comments on old pictures or posts. Check to see if he has added you on multiple social media platforms.

Article: A few different bright colors will give you the best results. You can use up to four different colors.  You can select a set of colors to create an ombré effect. If you pick colors that are a similar hue but with different shades, you can fade from one to the other. You can also go from one hue to another that's next to it on the color wheel, for example yellow to orange.  Other types of string, such as yarn, can work for hair wraps. Just make sure whatever material you're working with is colorfast. You don't want the dye to run the next time you shampoo your hair. It should also be fairly thin to keep your hair wrap from being too bulky. Thinner braids work better for hair wraps than thicker ones. Make sure your braid is very tight.  Picking a strand closer to your face will have a bigger impact than one further back. If your hair doesn't hold braids well, you can secure it with a small hair tie at the bottom. If you already have your hair in braids or dreadlocks, you can add a splash of color by selecting one or more strands to wrap individually. You will need four separate strings that are roughly two- to-three times the length of your hair. Remember that it's much better to start with too much thread than too little. You can always trim off the excess at the end, but you can't add length to string that's too short. You can always position the knot lower on the braid if you want your hair wrap to start further down. Overhand knots are the simplest knot you can tie:  Make sure all four strings are parallel and bunched together so they can be treated as a single string. Loop the strings behind the top of the braid. Make sure that your braid is positioned in the center of the strings so that each end is equal. Take the right end and loop it back around the braid to the left. Start by crossing over the front of the braid and pull the end under and through the loop back towards the right. Pull both ends in opposite directions to tighten. Make sure your knot is very tight when making a hair wrap.  Once the knot is complete, each string you started with will be divided in half. Before starting your wrap in earnest, you'll have twice as many strings to work with. For example, if you began with four strings, you should now have eight individual strands hanging from the base of your wrap.
Question: What is a summary of what this article is about?
Get some embroidery floss. Pick out a small lock of hair and braid it. Measure out and cut appropriate lengths of thread. Tie the threads around the top of the braid using an overhand knot.

Q: If you work with a group, you can brainstorm together to come up with energy-saving ideas. Plus, the more voices you have supporting you, the more likely you are to be heard by the people in charge of making energy-saving decisions at your school. Try organizing a group that is open to all students who want to work together to help the school save energy.   If you are a student, walk or ride your bicycle to school whenever possible.  You could then go a step further by inviting other students to join a group in school. You could also ask your teacher if they would spread the word and maybe even let you use the classroom for meetings. If you are a teacher, you could recruit students and help them by giving them ideas for how to save energy at school. One other great way to get students organized is to start an official school club. Check the student handbook or talk to an administrator at the school about how to get started. Either as an individual or as a team, create and post signs around your school. Try posting signs that remind people of specific things they can do to save energy and also some signs that raise awareness about saving energy in a more general way.   If you are a student, you could create some signs on your own or with a few friends who are also interested in helping your school save energy. Make sure to get permission to hang the signs first. If you are a teacher, you could have your students create signs for a class project or homework assignment, and then go around posting the signs together. For example, you might hang up signs next to light switches around the school with reminders, like “Remember to turn off the lights when you leave!” Recycling is a great way to save energy because it reduces the need to produce new materials. If your school does not already have a recycling station, then ask your school principal if you can set one up. Your school’s garbage company may offer recycling services. Check with them first to see if they can provide receptacles, and then ask them to place these in designated areas throughout the school. There’s only so much you can do as an individual student or teacher, or even as an organized group. If you want your school to make major changes, such as purchasing energy-saving appliances for the classrooms, waterless urinals for the boys' bathrooms, and dual-flush toilets inside all student bathroom stalls; you’ll need to get the administration involved.  If you’re a student, circulate a petition among your fellow students or organize a meeting between the administrators and your student energy-saving club. It can also help to get teachers involved. Support your case by doing some research and writing up a formal report. Include statistics to demonstrate how much money and energy the school would save by making the changes you’re suggesting.
A:
Organize a student energy patrol. Post signs about conserving energy. Set up a recycling station at your school. Approach your school’s administration about making big changes.
