What is a one-sentence summary of the following article?
If your crush doesn't know you exist, try introducing yourself. If you're in a class together, you can use that as an excuse to start talking to your crush. For instance, say you have history class together. You could say, "Hi, I'm Janie. We're in history together. What did you think of that boring lesson Mrs. Johnson gave the other day?" or "Hi, I'm John. I sit across from you in math. I was wondering if I could borrow your notes for the last class." See if you can get the person to spend time with you. If you're able to hang out more, you may be able to make friends with the person. Start with hanging out at school first. Maybe you can eat lunch together or spend some time together in the library. One way to get to know a person is to let them talk about themselves. Question them about their lives, such as asking them about their favorite color, their family, or their favorite books and movies. It's important to listen to the answers, too. That is, pay attention to what's being said. One way you can show you're listening is by making comments on what the person is saying or asking related questions. One way to build a friendship is to laugh and have fun together. Share a book of your favorite jokes with the person or giggle together over a silly picture. Having fun together can bring you closer. Lend the person your book when she asks. Bring an extra cookie to school for him when you make some for yourself. Offer to take down notes if she's going to be gone for the day. Little kindnesses like these go a long way towards building a friendship.

Summary:
Say hello. Try to hang out with the person. Get them talking about themselves. Make him or her laugh. Be nice to him or her.
