Sometimes I'm getting into pointless quarrels with my little brother, and that's very annoying indeed.
He just doesn't get it that he should shut the hell up sometimes, and the most important part for him in these cases is to clearly stress that I'm "pissed off" and so on.
This is the typical scenario:
HIM: "Hellooooo!"
ME: "Mm, hello..."
HIM: "What are you doing, huh?"
ME: "Nothing special, really..."
HIM: "Hey, what the hell is the matter with you, are you ANGRY?"
ME: "...Ehm, no, why?"
HIM: "Damn, you sound angry. What's the matter, anyway?"
ME: "You think I'll feel better from your telling me I'm angry?"
HIM: "DAMN, you're pissed off, ffs! Stop this already!"
ME: "Just keep quiet..."
HIM: "What's wrong with you?! I can't talk to you, damn it, you're being so angry."
ME: "Shut up, I'm in no mood to talk right now..."
HIM: "Oh well, you could just keep being annoyed like that, then, I don't mind, it's not my problem, but what the heck, stop being like that, damn it!"
ME: "WHAT? YOU are the one who keeps annoying me, SHUT UP!"
HIM: "You're so damn hopeless."
And so on.
This sucks.
