Yes, I'm in a wheelchair. This doesn't mean I'm unable to do things. It does mean I do things differently. I'll use the handle on a door to get through the door, so you opening the door may have inadvertently made it harder for me. Please don't push my wheelchair without asking. I can't state this forcefully enough. Nothing will send me from zero to furious faster. There is one and I stress only one person who is allowed to do this and I'm married to him.
