When I walked into the apartment I shared with a friend, and it was covered in vomit because her dog ate a pillow and had puked it up.
Two days earlier.
The living room was covered in dog puke and she had just sat there in the middle of it. She thought it was funny.
I called a moving company on the spot and arranged for the first appointment they had, and put my stuff in storage while I found a new place.
That was my last roommate.
