Okay...this broke me up!
For those of you who may not know Joan well she has a wild sense of humour! We spend a lot of our time laughing together.
She was showering me a couple of days ago which is quite a feat in itself as I am pretty much a quad at this point. Half way through the shower Joan placed the head of the hand held shower in my lap where I usually steady it while she shampoos me. My arms have deteriated to the point where I only have a bit of movement in my thumb. The shower head started to slip away from me and spray Joan. She immediately quips "Come on Rick, you have a thumb, use it!" We both broke out laughing until we almost cried. A merry heart does good like a medicine.
Moral of the story: So, just remember next time when you think you have nothing left....If you only have a thumb...use it! LOL
