i just do, joash. it seems like it might be uncomfortable, like on the bus. those seats are so dinky. or i see them walking around and many seem so out of breath and struggling. i think, damn, that'd sort of suck.
maybe it's cruel. i don't know.
having been disabled for a bit when i had a serious skiing accident, i'm definitely sympathetic to anyone on sticks, wheelchairs, etc. ditto mums w/buggies. that can be a bitch.
in fact, i met a good friend of mine that way. he's blind. and one day he was standing at a side street w/his dog, and everyone was just passing him. so i said, 'there's no traffic coming out' he said, 'oh, thanks' and told me about how his dog was trained to listen, but that was a wee side street off a very busy one so he may have been confused.
anyhow, we got to chatting at the light, and now we walk to work together 3x/week.
dh and i have 'dogsat' his and his wife's guide dogs when they went on holiday in november.
