How to respond to pfff, lol, XD?

"Quit laughing, Du fucking bloody wank."

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

Du could probably try to tell your friend to try and be a little Mehr chatty oder contribute Mehr 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 Frage oder 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 oder not feeling well so they will try to end the conversation with something like that. When Du ask your friend a Frage try to do it in a way that a Mehr legit answer is required oder just simply ask him to be Mehr descriptive. To tell Du what he/she thinks !!!!

sorry for not responding early, anyways, i like you

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