My son, Jaron, has autism. If he's not interested in something, he's quick to move on to the next thing. Even his most favorite TV shows only keep his interest for a few minutes. He'll rarely get through half an hour of anything, let along a full-length feature film.
Then you have to add that we're in a strange places surrounded by strangers. Thanks to Children's Village and the Yakima Theaters, my son was able to see a movie for the first time -- and he sat down the entire time!
