No problem. I saw this yesterday and this thread actually contains some compassionate responses.
I haven't read the other comments on this thread but there's a reason I don't take my 7 year old to the movies and that's because I think he would be too noisy.
We do go to live shows like Sesame Street Live where audience participation is expected and he doesn't interfere with other's experience in that environment.
I heard the mother on the radio this morning. Sounded like he was more affected by CP than by Autism since he knew how to scribble letters on a paper to communicate. I think it was his attempt to get his parents attention that got the other theater goers attention as well.
