Dad again

My dad can't go 24 hours without insulting me. Okay, so we've only got AC in one half of the house, so we've got a sheet over the hallway entryway to keep the air in, kept down by a metal bar. I always make sure that I replace that bar, and the ONE TIME I forgot, my dad gets on my case. I tell him, "I already knew that I should have replaced the bar." and then he says, "No you didn't" and he says it like I'm a 5-year-old. God dammit, I don't think he has any right to tell me what I do and don't know! Fucking, asshole, son-of-a-bitch, bastard!!!!
