What do you think of me spilling milk and then not cleaning it?
"Why would you spill milk so I can clean it up?"
I have better things to do than clean milk.
But why spill it in the first place? You should clean it up if you spilled it.
Why don't you clean it up? By the way, it's not a big deal.
You made the mess, so the expectation is that you clean it. How would you feel if I spilled milk everywhere and then left it for you to wipe up?
