In one sentence, describe what the following article is about: It can be tempting in a group discussion to go off on a tangent. In fact, it can be a lot of fun. However, try to stay focused on the discussion at hand, so you and others will get the full benefit of the discussion. Being in a group discussion is not just about saying what's on your mind. It's also about listening to other members in the group. While what you have to say is important, it's also important to let others have their say, as well.  To listen well, don't just be thinking about what you want to say next. Actually hear what the other members are saying. Try jotting down short notes on what others are saying, so you have them to refer back to. If you have a good idea, hold onto it until the moment is right to share. Don't cut people off while they're sharing their ideas. It can help to jot down a few words to help remind yourself to share your idea once it's your turn to speak. When a discussion starts getting heated, it can be tempting to start attacking the person. However, you need to stick to discussing ideas to keep the conversation civil.  For instance, you might be tempted to say, "Well, you're stupid for thinking that." However, that will only cause the conversation to spiral downward. Try, "Can you explain to me why you think that? I disagree, but I'd like to hear more about your side." This sentence will help dialogue continue to flow, and they may make a point that will win you over. When making a point, include everyone with your language. Don't use sexist or racist language when speaking up, as it may make others feel excluded.  For instance, try using "Chairperson" instead of "Chairman." Say "Can I get everyone's attention?" instead of "Ladies and gentlemen, can I get your attention?"
Summary: Stay on task. Listen to what others have to say. Disagree on ideas instead of making personal attacks. Pay attention to your language.

In one sentence, describe what the following article is about: The most effective way to keep your guinea pig safe from the heat is to move it from outdoors to indoors (if it isn’t already inside). The lower temperature inside your home will certainly help it stay cool, especially if you have fans or air conditioning.  Wherever you put your guinea pig, make sure it’s safe from any other pets or young children you have in your home. If you choose to place your guinea pig in the laundry room, refrain from running the washer or dryer while it’s in there. Guinea pigs are sensitive to loud noises and the machines will also give off a good bit of heat. If moving your guinea pig indoors isn’t an option, make sure the run is located in a shady spot and out of full sunlight. Being exposed to direct sunlight can cause the cage to rapidly heat to an uncomfortable temperature. Keep the cage in a shaded area of your home away from windows or under a small parasol. If you can’t bring the cage indoors, at least put it under a shady tree or under the roofing of your house.  Note that if wherever you put your guinea pig’s cage makes your guinea pig less visible to the naked eye, you’ll need to check on it more often just to make sure it’s ok. You can minimize the amount of sun that seeps through your windows by covering them with room-darkening curtains. The heat can be twice as bad in poorly ventilated places like these, especially as the humidity level rises. Wherever you choose to keep your guinea pig’s cage, make sure the location is well ventilated and has a good flow of air. Housing your guinea pig in a shed or garage can lead to death, so please take caution! If you’re using a fan, point it away from the guinea pig instead of directly onto it. Fans can help cool the air, but the feeling of having air constantly blown at it can stress out your guinea pig. Make sure the air in the cage doesn’t get too cold as a result of using air conditioning. Your guinea pig’s cage should never be colder than 50 °F (10 °C). Place a stand-alone or wall-mounted thermometer immediately adjacent to the cage to get the best reading of the cage’s internal temperature. Make sure this temperature stays between 65 and 75 °F (18 and 24 °C). This is the ideal temperature range for guinea pigs. Your guinea pig will enjoy lying down next to these items to cool off whenever it gets too warm. Plus, they help to insulate cold air in the cage. Gel cushions and cool tiles can also be used instead of ice packs or frozen water bottles.  Plastic water bottles can be filled with water and then frozen overnight. Wrap them in old tea towels or flannels and place them into the cage. Old tiles can be placed in the freezer to cool overnight and then put inside the cage for your guinea pig to rest on or near. Chilled gel packs can also be used as long as your guinea pigs won't chew them! The dampness can help insulate cool air in the cage as well as reduce heat stress. Rinse the cloth in ice-cold water and make sure you drain it off afterward. Make sure you only cover part of the cage to ensure that you can see the guinea pigs and they can see you. Avoid placing the cloth over the food bowl, as this can end up spoiling the food pellets in the bowl.
Summary:
Move your guinea pig indoors if you normally keep it outside. Avoid putting your guinea pig’s cage in any direct sunlight. Refrain from keeping your guinea pig in a shed or garage. Use fans and air conditioning to keep the cage cool. Use a thermometer next to the cage to monitor its temperature. Place ice packs or frozen water bottles in the cage. Consider partially covering the cage with damp cloths and towels.
