If a girl/boy that u like says hi to you but u know shes/he's taken what do u say back

personally u should stay just friends for a while and take it from there

I like this boy in the year above me but he has a gf what should I do?

You can still have a conversation without it going anywhere in the future you can ask her out if you still like her/him and she/he is single.

He only said hi, haha, you can still be friends even if u like him don't ruin there relationship tho, because if you do, it will turn out to be he won't like u at all and neither will his partner x

That's a dumb question u can still talk

Stalk him

@watthafuk o yea totally lol

Don't be awkward. I say get to know them first.

Say hi back it's not that serious lol
