He like my sister, i like him! help!!?

-There's a guy I like but I guess his mom told my older sister who is going to be 21 very soon that he liked her. But hes weird and always calls my sister by my name. He's 16 though and she doesn't like him and would never date someone that young. I think he'll get over his crush though. But for now how should I deal with it. Should I just watch it happen or what! Please help!If he has an inappropriate crush on your sister, he won't be a great boyfriend.



I'm not saying to reject him. He may be an OK guy but crushes are immature.maybe the mother got the sisters wrong?
