Good that he is OK
My wife has had a jinx going where something bad has happened on each of her major birthdays. Several years ago, her 50th birthday was coming up, and I had thought that I would beat the jinx by planning a short vacation on Monhegan Island in Maine. We had set up babysitting, and left mid morning to catch the ferry to the island when my cell phone rang, and it was the secretary at my son's school with a message - "Please meet your son at the emergency room" - She didn't know any more than that, so we turned around and went to the hospital, with the dread which you know - for the hour and a half drive.
When we met him there, he had broken a collar bone, demonstrating a dive roll over a picnic table at school.
I am glad to report that the streak was finally broken with an uneventful 60th for my wife....
