Hey

A simple question. Whenever a girl or a guy throws at me a shit-test, I use the agree and amplify.

Girl: I am sure you have no life haha :D

Guy: I have no life at all, how did you know? haha

Girl: I meant you don't know how to live (attempt to correct and begins to be angry)

Guy: You are right, I don't know how to live at all. You seem to know, teach me haha

Girl (gets really angry): I don't have time for this (and walks away)

How should I deal with this situation correctly?
