It depends who is asking, if it is a friend of yours or not.
If you agree and the person is a friend you say,
'Yes I thought about it and I agree, fair point.'
If you disagree and the person is a friend you say,
'I disagree, I enjoy it, its means a lot me and it's what I choose to do'
If you agree and the person is a not a friend you say,
'Whatever man' (better to walk away then be insulted/angry and get into a fight over it.
If you agree and the person is not a friend you say,
(say nothing, ignore them and walk away that person does not deserve any answer)
Why not!
Guy says : What the f`ck! You say: WHAT!
When he says it
Say thanks.
It means what it says
Say hi back!
It depends what 'they' are
I would say sure
you just say "sorry can you say that again (please if needed)" :)
if a guy say he loves u and them he dont talks to u he is not the one for u
Most of the time they either say that to be cool or if they like you. I am a guy myself and i say that so i know.
I suppose he says that when he doesn't care.
