<font color="purple">You're not whining.
I don't think it is so much as judging when people ask or stare, so much as it is curiosity and a tad of ignorance. I have a tendancy to do the same thing with staring and at least thinking about asking whenever I see someone in a wheelchair- and I don't even mean to (infact I feel kind of bad about it)
As for the people who just watch you have trouble with doors and stuff- they should at least help. </font>
