I broke my arm badly enough to require surgery. Afterward, I had to see an occupational therapist. He showed me how to get on and off a toilet, which I'd already figured out how to do. He showed me how to cook something in a frying pan, which didn't work in practice. (I lived on canned beans, frozen dinners and take out until the cast came off.)

What he didn't show me was how to put on and take of a bra, which, being a D cup, I kind of needed to know, or look after my long hair. I managed. I even managed to medicate my cat with one arm in a cast. (You need both legs and a blanket, also a very good natured cat.) But he wasn't what you'd call helpful.
