It’s the way he makes you smile, how every joke he tells you is hilarious. How he can annoy the hell out of you one second, and make you feel like someone special the next. The way he says your name makes you weak at the knees. You start catching yourself looking his way more often, hoping he’s looking at you too. Then you start getting nervous whenever you talk to him, his instant messages become more meaningful to you, even if you can't remember what he was talking about and that’s what makes you know you love him.
