How can you tell when a boy fancys or has a crush on you?

if he's the quieter type, than he may-

-stare at you a lot

-go out of his way to be with/near you

-act nervous or akward when around you

-avoid eye contact

or if he's the smooth confident type he will-

- be especially boastful when around you

-go out of his way to be with/near you

-try to make you laugh a lot

-shoot his friends 'i told you so' glances every few minutes
