Dear ((((((((((((Griffe)))))))))))
I do understand where you are coming from. My only benefit, at age 21, is that I've been in my manual wheelchair for my entire life ... so I've gotten used to it, at least on the "good" days.
Having a wheelchair isn't fun where people's misconceptions are concerned, sadly. I know a lot of well-meaning people who ask because they want to learn, but some people just ask "for the heck of it". I've had some pretty personal questions asked of me as a person... like "can I have sex".

I don't mind it when younger kids ask me questions, because they're coming from it with a more open mind than most adults.
Some people are understanding... but the ones that aren't, we've got to teach them a thing or two about how to act around a person with a mobility impairment, because otherwise they'll continue through life treating all people with wheelchairs as invalids or aliens from another planet.
If you want to whine some more, you can always come talk to me... I've got lots of fun stories.
