Are you ashamed of anything you've done /bant/?

When I was a child, I got into an argument with my brother, who was mentally challenged. I can't remember the specifics, exactly but I'm sure it wasn't anything serious. Anyway, it came to a climax when I finally yelled at him "DO YOU KNOW YOU HAVE AUTISM, YOU WILL NEVER EVER BE NORMAL."

What I didn't know was that my mom walked in right as I said that. I'll never forget the look of pure disgust on her face.
