My dad right now, for the following reasons (and I realise some of these are pedantic):
-Leaves the fridge door ajar because he doesn't make sure it's closed, ignores subsequent frantic fridge beeping
-Doesn't take a half-second to click pens closed (about 40% of our pens are actually usable)
-Doesn't reset the timer on the microwave after ending something early
-Dozes in the living room in front of the TV instead of just going to sleep
-Leaving the top light and end-table light on while dozing
-Leaving lights on in general, EXCEPT the garage light (which we want on)
-Restarts the computer whenever he has a problem with the browser
-Uses the bathroom, leaves the door open, doesn't flush, DOES NOT WASH HANDS WTF
This stuff grates on you after a while, I think.
