House rules: Cleaning up after yourself?

Not just for children, but for the adults as well.
I understand chores such as cleaning the bathroom and cleaning your own rooms.
But what about messes you’ve made? Do you expect whoever’s home at the time to clean it up if you have to leave? Would you be upset upon returning to see that your mess was not cleaned up?
On the other side, do you not clean something up if it is not your mess?

This is a survey on responsibility I’m taking. Thought I’d put it to Fluther for more insight.

Thank you!
