There are two people in wheelchairs around my way that I always try to avoid. One is, reputedly, a drug dealer, and doesn't have a motorised chair, but always seems to find younger 'helpers' to wheel him around (he's around fifty I'd say) and the other is a foulmouthed Scot, always with two others, cans of lager in hand. I'm considerably older than either and walk very slowly and crookedly with a stick, and most people are considerate. These two would have me knocked over in the street without a moment's thought if they considered themselves impeded for a moment by me, and one in fact did just that in our small Co-Op last week. I was fortunate that a shelf prevented me from falling to the floor. My point is that disabled people are no better citizens than any other and one who's grown up anti-social (perhaps not having been disabled at that stage) isn't suddenly going to become virtuous. I have to admit one of the reasons I resist getting a mobility scooter is the bad reputation some of their users have, and I don't wish to be tarnished with the same brush.
