I'm not going to do work around the house.
Why are you refusing to do your share of housework?
I'm going to pay a teenager to do it.
Doing your share of the housework will show the people you live with that you respect them. Don't get somebody else to do it for you.
Why it doesn't matter who does it? I'm just trying to get things done right.
It is good to get the place clean no matter what but by doing it yourself, you are showing them that you care and respect for them. It would be good to do it once in a while.
