Yes, me too. You should not assume someone who seems able to stand and walk unaided is not in need of assistance for longer periods. It can be a matter of scale

Yes, me too. You should not assume someone who seems able to stand and walk unaided is not in need of assistance for longer periods. It can be a matter of scale, and there can be sudden tipping points. The person I know is perfectly able to stand for a short while, or walk around a shop or food court for a couple of minutes carrying items with really no obvious problems. But navigating an airport all the way through, quickly making it to a connecting flight on the other side of a large terminal, or standing for minutes in a check-in line is basically impossible without days of pain afterwards.
