You know how guys can get into a fight, be it physical or a heated argument/feud, and eventually bury the hatchet and even become friends, and the animosity from the past is totally dead?

Well, with women, every single perceived slight is remembered until the day she develops Alzheimers or dies. She'll pretend to "forgive" you, but 90% of a woman's peanut-sized brain is the designated "this person wronged me" portion. And what you said or did that upset her will be easily accessed any time she wants to pull it out.

You could be having a totally unrelated argument, and she'll remind you about how at 5:43 PM on October 14th, 1982, you accidentally threw away leftovers that she was planning on eating, you Insensitive. Piece. Of. SHIT. You clearly don't care about her AT ALL.

Is there anything that is sincere about women? They can't even be sincere about the fact that they're insincere.
