Sometime during the day, my cat threw up a hairball in my bed. My unmade bed, so that the mess landed on the sheet and soaked into the mattress. Yuck. Grr.
With my eyes hardly open, I went off to get stuff to clean it with. Of course, once I was done, it left that place on my bed wet. She was watching me clean. I turned to look at her and glared as I informed her, "*You* sleep on the wet spot tonight."
