How to respond to pfff, lol, XD?

"Quit laughing, آپ fucking bloody wank."

I hate it when people do that. It's hard to respond to stuff like that.

آپ could probably try to tell your friend to try and be a little مزید chatty یا contribute مزید to the conversation.

Repeat them.

I have seen it happening a lot. It depends on the subject you're talking about. There are times when people might not know how to respond exactly to a certain kind of سوال یا comment. It's an awkward situation so they reply as simple as they can. Of course there is always the possibility that they might not feel like talking, being busy یا not feeling well so they will try to end the conversation with something like that. When آپ ask your friend a سوال try to do it in a way that a مزید legit answer is required یا just simply ask him to be مزید descriptive. To tell آپ what he/she thinks !!!!

sorry for not responding early, anyways, i like you

I just assume that the conversation has reached its natural conclusion.
