I'm not going to do the dishes because I am sick.
Is that the only reason you are not going to do the dishes?
I'm not doing the dishes because it's a stupid chore. I feel more comfortable lying in bed watching TV.
Even if your sick, it's still important that you wash the dishes. If you don't then they will build up and become a bigger mess.
I live alone now so it's okay. I just don't feel like doing the dishes.
It okay to not do the dishes immediately, but it's still a necessary chore that you need to do. I understand it's not a good time, especially when you're sick, but sometimes there are chores that have to be done regardless.
