I do all the cleaning. I live with my disabled, elderly mom, and since she's at home 24/7, she makes a lot of mess. Dirty dishes, crumbs on the couch/carpet, trash and recycling that needs to be taken out every few days, etc. And other problems that I won't talk about here.
Plus she has two cats, and those lil' fuckers (<3) kick up tons of dust, dirt, and hair. And then there's all the messes I make myself!
Luckily, my mom and I aren't major clean freaks. I just do dishes every other day, and then do heavier cleaning on the weekends: vacuuming, sweeping, mopping, replacing the cat litter, etc.
It's exhausting. Especially after living with housemates where chores were shared. But my case is a bit different, I guess, and I have to take care of it all.
