I used to work for a while with blind people. The boss of the local blind people community was shooting dad-like jokes about blindness all the time, I loved that attitude!
It helped to make connection with these people and we needed that, because I was developing some app that main audience was blind people and to actually understand their needs and problems you need to make a connection with them.
Decade or so ago I was once in a room with a group of people where one person was blind. An acquaintance of the blind person came into the room and said oh hey good to see you to him. The blind person replied back to them with one of the best comebacks I’ve ever heard in my life with “well I’ve never seen you” before” and had the whole room laughing.
