Deck the halls, the walls, and the toilette seat...?! I seem to be the world's first (that I can find) actual mood ring.
At the beginning of my pregnancy and again at the beginning of two very bad flares of whatever the blinky-blank I have my tushy turns the toilette seat a lovely shade of blue-violet-ish. You can plainly see where my skin touches (tush and legs). And no, I don't sit there perspiring. I actually have a very difficult time sweating. Sheets also turn slightly bluish but not as noticeable. I reven uined a seat trying to clean it off.
Anyway, I wondered if this rings a bell for anyone. I've only had the nerve to mention it to one doc and saw where he thought conversion after that apt.
I also turn white shirts bright pink if I get really stressed. No smell, just a pink streak down my back from persiration. After one rather nasty rin-in at work I had to go buy a new shirt for the office.
