"Rock Star" - not Cleaner

I asked Julia to clean up her area.  Then later in the van, I asked her to pick up some stuff on the floor. This is what she said to me: " I am a Rock Star and an Artist, not a Cleaner."
Then she proceeded to tell me "You boss everyone around & we don't like it."
I said something about even rock stars & artists were children who cleaned up after themselves!

Apparently there has been discussion among my family members.
THEY don't like being bossed around!

My response - clean up your stuff. Simple! : )
