Scene: at home, Saturday morning, sitting at the dining table
A: (looking at the bank account statement) What the fuck! What did you buy? It looks like you spent 1000 € last month!
B: I needed some things.
A: What exactly did you need! Our apartment is already full with crap that you bought since you moved in!
B: What I bought is not crap. You just don’t understand. There are some things that I need.
A: Are you going to tell me what they are?
B: No. Why should I?
A: I work hard for the money we have, and you go and spend it.
B: I work hard, too. My job doesn’t pay as much as yours, so I need to use some of the money you put into our joint account. Sort of a compensation for how shitty you treat me.
A: You asshole! I don’t treat you shitty!
B: Yes you do! You just called me an asshole. That is an example of treating me shitty. You are an asshole, not me!
A: I don’t treat you shitty, I can call you whatever name I want, and you can’t just go spending money before you have asked me for permission!
B: I don’t need to ask you for permission to do anything, asshole.
