There are a few things people feel the need to say before they actually think that irritates me to no end. It's usually involving my health. (Which is pretty bad.) "Oh, I understand." Um, no you really don't. Quit saying that. "How are you?" This said by people who actually know me, and are just trying to be polite.. you really don't want a 30 minute diatribe so don't ask. "Well for someone so sick you look good." Just because I put on some conceler and try to cover up the dark circles to cover up the zombiesque look does not mean I'm feeling better. Bah.
when i felt bad and when people would drive me crazy with questions like that, i had periods when i would experiment: id started explaining how bad i am, what is wrong with me... i never ever said "oh, im good" just to comply with the politeness stuff.. if i didnt feel like explaining, id just say "bad, cant you see" anyway, i hope you get better)
When someone says something and sees that you were offended, they try to backpedal and say "I didn't mean it". Of course you fucking meant it, you just fucking said it.
