Vacuuming, because I'm a total wimp with our heavy ass vacuum cleaner, and it takes a while for it to vacuum all the hair that's somehow on my room's floor. I shed like a damn dog for no reason, so I have to do it tomorrow. And I have to vacuum my bathroom counter too since each time I dry my hair, random strands will fly off and accumulate around. As with the floor and other places.
Cleaning my shower isn't as bad until I end up soaking half of my shirt trying to rinse the cleaner out. And no matter whether I turn the air vent and open the doors or not, the fumes accumulate and make my head/nose ache. I've had to use a broom before to clean the soap scum off my shower floor (some soaps are weird about how stubbornly they stick)
I personally hate doing the dishes because we usually have so many to do. The worst part about cleaning it is the mushy food that you feel on your fingers, it's so gross! I also hate the fact that I get food under my nails. Ew.
