So if you've ever been someplace with one of those horrible institutional waxed tile floors, and there's a mysterious blotch that looks much paler and cleaner than the rest of it? Cleaner than bleach can get it? Now you know. Puddle of human blood.

I did wonder about that on my parents' kitchen floor. Now I wish I hadn't, really. (Very old building.)

Glad he found where he could get help and I hope he continues to do so!
