So in Japan, it's just Not Done to wear your shoes in the house, for reasons of cleanliness. You go barefoot in the house, unless you're hitting the head: there's a pair of slippers for that.
So... What's proper etiquette around this question for someone in a wheelchair? I imagine that most efficiently, you just all are polite if you wear your shoes in, since wheelchair-bound person is effectively doing the same.
Also, a traditoinal home has an interior area that's a step downwards, where you take off your shoes. If you're living with someone on wheels, there is presumably a ramp for her/him. When's that ramp 'inside' instead of 'outside' space?
These are the thoughts that preoccupy me en route to an RL friend's: if you know those I know RL, you can probably guess easily who I'm visiting.
Please answer any of these questions if you know the answer.
