Pro tip for men: The reason she won't tell you why she's angry is because you'll just argue and do the same thing next time.

Yeah that's why I like being alone. Nobody arguing with and negotiating how I feel when they act clueless to the point of rude. No eggshells to walk on knowing I won't get the same courtesy. No disappointment when I realize my feelings don't matter.

That's not why I'm angry...

"If you don't know, then I'm not going to tell you."

"If you don't tell me, I'm NOT GOING TO KNOW!!!"
