Doing
light cleaning before the cleaning lady comes to preserve your image or
keep her from seeing how you really live.
I've got to pre-clean my house so my cleaning lady won't see all the
condom wrappers and beer.
Friend A: I'll have to meet you later, I have to clean my house.
Friend B: Why??
Don't you hire someone?
Friend A: Yea but I gotta pre-clean so they
don't see how messy I really am.
