Day 15 – Warnings – What do you feel it most important to warn for, and what's the strangest thing you've warned for in a fic?

I hate warnings. I only use them to prevent the whining of narrow-minded people who tend to throw a tantrum on my review board when their tender sensibilities haven't been taken into consideration. I especially hate homophobes who want to have a warning when a male character smuggles a single flower into the room of another male character (yes, it happened). The strangest warning? PG for heavy poltical troubles. *g*
