Article: The average age for a girl to get her first period is about 11 to 14 years old, but some start much earlier or later. It is perfectly normal for a girl to get her first period anywhere between the ages of 8 and 15.  Most girls do not start their periods until they weigh at least 100 pounds. If you are a bit behind your friends with growth spurts, your period may start a bit later, too. It's nothing to worry about, so just be patient.  If you haven't had your first period by the time you are 15, or within three years of when your breasts first started to develop, you should consult a doctor. If you get your period much earlier or much later than your friends, you might feel different than everyone else. You might get your period when you are 9 or 10, or not until you are in your mid-teens, and both are perfectly normal! It's important to understand that all girls get their periods at different ages. Genetics play a huge role in determining when you will get your first period. Try asking your mom and sisters when they got their first periods. While you're not guaranteed to get yours at the same age they did, there's a good chance that you will be around the same age they were.

Problem: Article: If you want to really seriously prank someone: wait until the owner of the doorbell closes the door to go back inside. Then, sneak back up to the door and ring the bell again – even more obnoxiously this time! Remember: each time you re-ring a doorbell, you run a greater risk of getting caught.  Don't take it too far. If you ding dong ditch one house more than two or three times, then the owners will begin to get frustrated. They might wait by the door to catch you – they might even call the police! Do not be malicious. At some point, you are just being cruel by endlessly tormenting the same person or family. Remember that you're disturbing everyone in the house, not just your friend. Once you're satisfied with your ding dong ditch on the first house, move to a different street and locate your next target. Pick another friend or another person you know. Bike, walk, or drive to the next location and repeat your procedure. Have fun, but don't be careless! If you let your guard down, then you might get caught.  Play until you've had your fun. Remember: the longer you stay out playing ding dong ditch, the more likely you are to get caught – especially if you are repeatedly hitting houses in the same neighborhood. On one hand, it's easier to get from house to house if you stay within a single neighborhood or a few blocks. However, if you hop around and hit several different neighborhoods, you and your friends will be harder to track down. Remember that this game is all in good fun. Ding dong ditch can bring you and your friends together, but it also impacts the lives of the people whose doorbells you ring. Do not use this game to harass or target anyone. Have a good time, but don't get too carried away. If you take it too far, then you might damage friendships, get in trouble, get the police called on you, or worse. Depending on who catches you, you might choose to play it cool or to own up and apologize. Read the situation and know when to give yourself up.  If you're standing on someone's porch and they open the door before you can get away: just pretend that you are visiting them, or that you are coming to ask about something. Pretend that you are distributing fliers, or delivering a gift, or coming to borrow some sugar. If you get caught in the act by your friend, your friend's parents, or a neighbor: play it cool if you can get away with it, but know when to own up to the prank. This is when you should apologize and say, "We were just trying to play a dumb prank. I'm sorry. It won't happen again." If you get caught by the police, it's usually best to just be honest. You might be able to get away with a cover-up lie – but the officers have probably seen this before, and there's a chance that they'll see through your story. If you are sincere and show that you've learned something from the experience, then they'll usually let you go with just a warning.
Summary: Ring the same doorbell again for effect. Choose more houses to prank. Don't take it too far. Make a plan for if you get caught.
