that question cannot really be answerd because its up to you
Deductive reasoning would indicate it meant you did not like each other.
You would probably say hi back.
Maybe he will ask: why? If the girl is his girlfriend.
Well I'm a girl so you will ask her friend her closet friend or best friend to ask her who she likes and if she says you you ethier text her or say i like you do you like me and if she says yes then you sy do you want to go out.
When a boy says they don't like a girl, they really mean, that they love the girl into bits!
To tell if a girl likes you you have to look at their expressions. If she smiles and says hi often then she might like you. Sometimes it's hard to tell.
Not every boy that says hello to a girl likes the girl. He may say hello to be friendly.
When a girl says thank you to you then you say 'you're welcome.'
Just say no you dont, you,re beautifull
Well i dont know how old you are but... Heres the winner you go up to the girl and you say to her has a man ever told you he would die for you... and even if she says no make her say yes... lol and then say well baby I would live for you....
go up to her and say would you like to come to such in such dance if she says no then there is plenty of other fish in the sea!
I am a girl and I would say that you should talk to her first saying, "Why do you like 'Mark'?" and if she says something like... "Becuase he is cute and funny why?" then tell her that you like her and that you could make her happy. If she says no then accept that she is happier like that. its all you can do.
