who only by moving can balance

I wish there were some productive way for me to communicate to humans at large that, if they see a lone wheelchair user Out And About, prior to approaching them they should ask themselves Two Simple Questions:

(1) Would the question I'm about to ask be kinda weird and intrusive if the wheelchair weren't present?
(2) Would I ask it anyway?

This enables people to e.g. stop and offer me a sympathetic cigarette because I'm clearly having stunningly obvious hysterics by the side of the river and have been for some time, while actively militating against... pulling their car into a lane they'd never normally be in, stopping, leaning over the empty seat to open the passenger-side door, and asking me if I'm okay.

I WAS PLAYING POKEMON.

I'M FINE.

PLEASE TELL ME WHAT GIVES YOU THE IMPRESSION THAT I'M NOT SO I CAN STOP DOING IT.
