I was watching the movie "when harry met sally " and I had a trouble to understand this highlighted part of their conversation. Thank in advance.
Sally: Amanda is my friend.
Sally: So you're going with her.
Sally: So you're coming on to me!
Harry: No I wasn't. What?
(Sally is not impressed, jaw drops, wide eyes)
Harry: Can't a man say a woman is attractive without it being a come-on? Alright, alright, let's just say just for the sake of argument that it was a come-on. What do you want me to do about it? I take it back, ok? I take it back.
Sally: You can't take it back.
Harry: Why not?
Sally: Because it's already out there.
