In one sentence, describe what the following article is about:

Using your body language to show him you like him means that you use subtle signals, such as facing him or touching his arm, that will hopefully catch his attention. Try to sit by him when you can, and when you’re talking with him make sure that you have your whole body facing him. Don’t cross your arms while you’re talking as this creates a defensive position.  Don’t forget to smile when you’re talking to him. Realize, though, that some boys won’t really be paying enough attention to notice your body language. He may feel too nervous around you to be paying any attention to subtle signals. Giving him a compliment will show him that you are paying attention to him. You can think about things he is really good at, or something you really like about how he dresses and compliment that. Giving him a compliment every now and then may give him the confidence to tell you that he likes you.  For example, you could say, “Hey! I just wanted to let you know that I think your outfit makes you look really nice today.” If he plays a sport, you can tell him how good he is at it, for example, “I saw your soccer game yesterday. That was a really awesome goal you scored!” Don’t overdo it. A compliment every now and then is OK, but giving a compliment multiple times a day may make him feel uncomfortable. A shy guy may be reluctant to look you in the face, but if you can, try to make eye contact with him. If you do catch his eye, flash a quick smile, and hold the eye contact for about 3 seconds. Then get on with whatever you were doing. If you are able to do this, he’ll get at least an inkling of an idea that maybe you’re into him. Making eye contact doesn’t mean staring. If you make eye contact for too long he may get embarrassed. It may be that you are only around this shy boy in front of his or your friends, so you may not get to spend much time talking to him. When you are together, try to focus your attention on talking to him without ignoring everyone else. Ask him questions about things he likes, or what he thought about a new movie that came out.  Try to ask questions that will require more than a “yes” or “no” answer. For example, don’t say, “Did you like the game on Friday?” instead say, “Tell me what you thought about the game on Friday.” If you are in a group don’t ignore everyone, just casually try to engage him in conversation while everyone else is talking. If you are alone this will be easy. He may seem as though he has nothing to say, but if you keep coming up with new things to talk about he’ll (hopefully) come out of his shell a bit. One of the most common ways to show someone that you like them is to simply flirt with them. When most people think of flirting, they think of doing it in person, but if that seems to scary, you can also try flirting with him over text message, email, or chat.  When flirting via text, use emojis. One of the most common emojis used when flirting is the winky face, which keeps things light and fun. Try to make a bit of physical contact when flirting in person. For example, if you are sitting next to each other you can subtly let your knee touch his knee, or you can brush some imaginary dirt off of his shoulder. When flirting, don't forget to smile! Flirting is supposed to be light and fun. If you are being very serious he probably won't think that you are flirting. Tease him just a little bit. With shy guys you definitely don't want to over-do this. However, teasing him just a little bit might show him that you are interested. When you tease him, be sure to smile and laugh, and maybe gently touch his arm to let him know that you aren't trying to be mean at all. Most boys like to be reminded of their masculinity. Getting him to help you with something may help him feel courageous enough to make a move. When asking him to help you, try to think of something that will make him feel tough. For example, ask him to lift something a bit heavy. Don't be unrealistic here, and make sure that you choose something he can actually lift. You could say something like, "Hey Josh, I'm trying to put these big heavy books back up on the shelf, but they're too heavy for me. I know you're strong, could you help me?"

Summary:
Use your body language. Compliment him. Make eye contact. Engage him in conversation. Flirt with him. Ask him to help you with something.
