OH MY GOD. My rooommate (that I kicked out of the house, due to negligence and general stupidity), would leave EVERY cupboard open in the kitchen...as if he were too lazy to open and shut them, so might as well just leave them open. With a house full of animals and dust, this is not a good thing. I also hate when my BF stands at the back door with the door open because he says his dog doesn't know he has to go potty unless somebody is standing there to tell him. My dog doesn't finish going to the bathroom unless you leave the door because he's too excited ... This just lets more cold air into the house. CLOSE THE DOOR!
EDIT: I have more. I'm a very patient, but easily annoyed person....
My BF is learning NOT to touch me when I am
A) In the kitchen (I yell at the dogs when they get in my way, I'll yell at you too.. no I don't want hugs and kisses while I'm juggling 3 pans and dishes.. get away from me)
B) Drawing. DO NOT BUMP ME. Warn me before you're going to get close, and if you insist on sitting on the same couch as me while I'm drawing, prepare for the evil eye and some muttered swear words as I express my hate for you for hindering my tasks. I have told my BF that if he bumps me on accident while I'm drawing (especially if it's something I am happy with) while trying to be 'smart' I will likely burn the house down with him in it. It's only deterred him slightly.
