The need to step over something at an entrance to something like a cafe. A person with most wheelchairs will likely be compelled to ask for assistance.
When I have an option to do things by myself rather than with and through assistance, it seems dignified to do myself. That is different from, say, collaborations when people assist one another. (Once we remain assistive oriented.) Should it feel any different to a person in a wheelchair? Indeed – should it be different when sorting a solution for all seems rather simple?
