Yes, and it could be part of the brain injury, too. After TBI some patients have trouble seeing the perspectives of others, reading body language, censoring speech, etc...

When I'm dealing with other TBI survivors, I try to be tolerant of their behaviour - and hope they'll do the same for me. "Norms", on the other hand...

I have little patience with non-TBI people who get angry with me because I don't want to be "super cripple" and/or embrace my injury as some opportunity for personal/spiritual growth. If they think it's so great, I'll help them find a wall they can pound their head against.

While it might not look that way to the ignorant, I'm doing the best I can. All things considered, that's pretty darn good.
