* He pays attention to you. If a boy is interested in you, he will pay attention to what you say and do. He may make eye contact with you, smile at you, or laugh at your jokes.
* He goes out of his way to talk to you. If a boy likes you, he will find reasons to talk to you, even if it's just to say hello. He may strike up conversation with you when you walk by in the hallway, make a quick run home if he sees you at the ice cream shop, or send you funny or cute text messages.
* He flirts with you. Flirting is a common way for boys to show their interest in a girl. If a boy likes you, he may tease you, give you compliments, or say things that make you blush.
* He tries to impress you. Boys often try to impress the girls they like. If a boy is trying to impress you, he may show off his athletic skills, make jokes to make you laugh, or tell you about his accomplishments.
* He asks you out on a date. This is perhaps the most obvious sign of all! If a boy likes you, he will eventually ask you out on a date. This could be anything from a casual get-together to a formal dance.
Of course, these are just a few general signs. Every boy is different, so there may be other ways that he shows his interest. If you're not sure whether or not a boy likes you, just ask him! That's the best way to find out for sure.
