Quite often, I drop one of my crutches, or both of them - normally when I am balancing them on myself or something else while I use my hand(s) for something else. As I am a touch-your-toes type of person it's no problem, I can pick them up without any trouble.
But how do obese people manage? Presumably they would have to stand there until somebody picked it up for them.
The other thing I have been known to do in the past is sleepwalk. The two memorable occasions were firstly when I took the duvet into the corner of the bedroom, heaven knows what I was doing with it. Mr H. wasn't impressed! Another time (he tells me, I have no recollection) in the days when we set the house alarm at night, I went downstairs, unset the alarm, set it again and went back to bed. I quite regularly wake up scared thinking there is a stranger in the room or in my bed (interestingly not once has that happened since the accident, but then I have been sleeping alone!); or not knowing where I am and taking a few moments sitting on the edge of the bed putting the pieces of jigsaw together - window, bed, etc. - before I finally work it out and relax.
So, if a compulsive sleepwalker breaks their leg - when they sleepwalk do they remember to take their crutches, or do they try and walk around without them?
