Yes, folks, it's true. I've asked two of them to do it because I can't reach it without having to stand on a padded chair with rolling wheels, which would surely result in me falling and cracking my head open on the toilet. So far, they've both said they would do it, and one of them even went in there and used the bathroom... in the dark.
Wow.
