Not clearing microwave time. The idea of not wanting to wait four more seconds is pretty illogical. Every single time I clear a microwave at home or work I say, “and now it’s a clock again.”
When my roommate leaves the cabinets open when putting something in or taking something out of them. After he puts his dishes away nearly every cabinet is wide open. It makes me illogically angry, like you already did the difficult part, why is it so hard to close a freaking cabinet?!?!
When people dog-ear a page in a book to mark it. No matter how cheap it was. Freaks me out. EDIT: Even in magazines. Cannot stand it. muaaaa!
