We were at the station the other day, luckily my H who uses a scooter when out, wasn't with us. We had to go up the steps, over the railway line, then down more steps as the lift was broken. Had my H been with us, we'd have had to go all the way home again and not go out.
This.
It's something people not dealing with disability often don't understand.
Leaving the house while disabled is something that can often still be done, it's just the logistics are incredibly fragile and everything needs to run like clockwork. If some quite small thing goes wrong, that's it, game over, go home. You don't have the flexibility to work round even quite minor issues.
It can be something apparently trivial: a car parked on the pavement or over a drop curb, a quarter of a mile from your home; an unfortunately positioned roadworks barrier or pile of sand; someone who's left the bins out 2 days early (and just forget about leaving the house at all on bin day).
