The PTA held their annual fund-raising carvinal at John's school last week. Matt took the kids and it sounds as if a good time was had by all.
Matt reported that he had a glimpse of what it must be like to be John. John spotted a friend of his, and while all the kids were highly focused on winning cheap plastic crap and so weren't saying much to each other, John did pull out of it long enough to greet his friend. The friend waved back, at which point John figured this was an invitation to give his favorite greeting, a bear hug.
The other kid pulled back and snapped, "Why do you have to be so NICE all the time?"
