I ended up staying with a friend. She has a roommate, and they both smoke. I ended up sleeping on a bed there. What I saw disturbed me greatly:
The pillow, sheet, and 2 blankets all had various amounts of burns from ashes and cigarettes. The sizes on some of the burns were so big I could fit my index finger through.
I have to wonder: how do they keep from catching their surroundings on fire?
