I'm not going to clean up after my younger sister's pet macaw that she has.
Does she try to make you clean up after her?
Yes, she complains how long it takes to clean up and strongly insists not to let it poop.
You should tell her to do it herself. She is the one that wanted the bird, she could clean up after the bird.
I'm not going to do it unless she ask me nicely.
And you shouldn't. Tell her that she needs to do it and take care of it herself.
