He will be confused and probably a little embarrassed that he likes someone (which he shouldn't) and as a result will try and hide his feelings by teasing or joking alot around you/at you. Don't worry about it, he will eventually work out his feelings.
he would act strange and wierd
Whatever you want, act on impulse.
There is many ways, for each boy, it is different.
If he likes you he won't get mad at you but if he does he woukd act like it never happened so yes he would.
different boys have different ways, some will just act flirty others might try and touch you if you know what i mean a shyer boy might just smile at you occasionally or you might catch him looking
He may act awkward.
try to act cool with him or u could do anything he likes.
Be a friend to her. Don't act jealous. Always be kind and caring. One day she might see what she is missing out on
You just act normal and tell her. Good Luck!!!
Same as he likes a boy. They blush and they care.
go up to the boy and flirt with him if he likes you he will act kind and flirt back if he doesn't he will say something like go away or he will just ignore you.
how you will know if a boy really likes you he will act all shy around you and he will blush sometimes. and when you talk to him he will not know what to say.! fingers crossed that he likes you honey!
