It's horrifying how many helpful people grab at wheelchairs (or one's body), and I've had several accidents that way. However, there seems to be a gradual change in attitudes and awareness of the helpful. I now rarely wonder if I should have accepted the offer of someone to fit my wheels with pointy metal à la Boudicca, as he had put on his mother's wheelchair!
