* She goes out of her way to talk to you. She may text you even when there's nothing important to say, and will always put in extra effort to talk to you in real life, even if it means going out of her way.
* She laughs at your jokes. Even when they're not that funny! She's just happy to be around you.
* She tries to impress you. She may show off her talents, or try to dress or act in a way that she thinks will appeal to you.
* She looks for opportunities to be alone with you. She may suggest you guys walk home together, or that the two of you go to a movie.
* She touches you. She may brush your arm or leg, or touch your face. This is a way of showing that she's attracted to you and interested in a physical connection.
* She's always around. She may turn up at your locker, or in the same class, even when it's not strictly necessary.
* She tells you. Sometimes a girl will just come right out and tell you how she feels.
