Anyone with a large enough social group will have some people like this. These are people who've engaged in football, boxing or contact sports like rugby. Or, people with severe ADHD. Or have had some kind of traumatic brain injury. These are real users and they're my friends.

If a messaging application can't be used by that person, then that's a default fail. I'm not going to expose them to it.
