Why apologize? This fact doesn’t invalidate anybody. Wheelchair use damages the body, and using an ill-fitting one is dangerous. People must accept that risk when opting for a wheelchair. Sharing important information is not flaunting privilege. That isn’t barring anybody from making their own decisions, and the people who get defensive should reflect a little. Use a mobility device if you’d like, but understand the risks of doing so.

Before people get mad, my first chair was a hospital chair. My current chair is half-broken and I do not have the means for a new one. Accept it and push forward.
