You know you're in love when someone is always on your mind and even if you want the thought of them to go away, it just can't. You know you're in love when even if you hear their name, you're heart begins to pound and your mind starts to race. You know you're in love when even if you just think of the person, you just feel happy and nervous.You know you're in love when you do things you thought you never would, but they would.You know you're in love when you're not afraid.
