I have Muscular Dystrophy but I can still walk. I have to use a cane. In this questioning, whoever B is, sounds like a person I wouldn’t want to have anything to do with. Sounds very shallow. Anyway, when I was a kid, we went to a theme park and inside are these really padded car like things. They have wheels, sides but no top. They have a rubber thing going around the base so that when they bump into something, they just bounce off. No wY to get hurt. Kind of fun bumping into each other. So, it’s called bumper cars. This was kind of a rude comment by B - to me. We would say. Is he/she in a wheelchair? There isn’t anything wrong, on A’s part by asking.
