At the station you see a woman in a wheelchair working her way up a steep ramp. It looks like hard going. You are right behind her and could easily push.
The principle
Wanting to help does not replace asking. Offer, then accept the answer. This goes for touching someone, their wheelchair, their cane or their assistance dog.
