Thank you both for your useful responses.
Carson - yes, lifts!! Have just been away on holiday, hotel lift was OK until there was somebody outside waiting to enter when I got out - I froze completely. Then found, as you said, being ready to walk as the doors open, worked well. Also used the stairs a lot, all 7 flights of them!!!
Never did cope with the huge revolving hotel entrance door - have been to this hotel many times before and never envisaged a problem. First time I froze about half way around and the door behind me pushed me along, didn't quite fall over, nobody saw thank goodness! Next time, I watched it carefully to get my pacing right, held my partners hand, froze again! Gave up with that & used side entrance instead. Enough embarrassments in the restaurant, self service style, freezing at counters etc without any more. Just had to keep telling myself nobody knows me . . .
And pulling a wheeley case - OK going in a straight line, but turning or slopping no chance.
Hey ho, more of a challenge than a holiday!
Fed - am thinking of trying a clip-on metronome to get a rhythmic beat going, the sort runners & swimmers use for pace training. Don't think I could stand loud music all the time. You sound as if you have great fun in your scooter, a real sense of freedom!!
