In my apartment:
I'm the only one who ever washes all the dishes. I can't stand a dirty sink. I also do the vacuuming, dusting, and cleaning/mopping up the kitchen/bathroom often. I guess my mom just raised me well.
The trash bags often collect in the common area, and I do admit to being lazy to take it out. Usually I end up helping one of my roommates take it all out at some point (every other week or so).
So I pretty much just do all the housework in the apartment despite me having a much busier schedule than anyone else that lives here.
The last thing that ticks me off is thermostat control. My black roommate walks around in fourteen layers of clothing when its 80+ degrees outside and insists on keeping the heater on in the apartment. I've finally taken measures to jam the thermostat to airconditioning (BEHOLD THE POWER OF WAX AND MEDICAL TAPE). I've also put a sign "Swimming Pool" above it for scare tactics.
