Thanks for sharing your experience. While not exactly the same, I've had similar experiences when I've been pissed off and feeling sorry for my situation and then I see someone else, not necessarily handicapped, but maybe vastly overweight or struggling with some other disability . . .
And I think, "Hold on how . . . maybe I don't have it so bad after all."
True, as 1Coopgt pointed out; it's a matter of perspective!
