I have become like a Chinese parent waiting, outside the school gate, for my child to come. Tuesday, waiting outside, I caught a glimpse of Tony at the front of a conga line of what must have been his classmates; and so I walked through the gate to catch his eye. One of the workers saw me do this and she said "Tony's Father! Tony will be out in five minutes!". She didn't see that Tony was right behind her.
I have noticed, as has my wife, that the people running the school are very touchy about security even to the point of separating parents from their children.
