Wow, makes my story seem tame! Ceremony went well and weather was great, but afterwards everyone streamed onto the football field to meet up; as soon as we found my S, he mentioned that he couldn't find his mortarboard (which had been flung in the air) and my DH immediately disappeared to search for it. We never did find him again until he called from home (a few blocks away). Seems I was the only spouse who remembered to carry a cell! My S went off to find friends, leaving me with my mother and brother who both wanted to go back to the house to eat (it was now close to 9 pm). My 80-year-old mother was especially concerned about my poor starving 56-year-old brother. I was on the brink of hysterics.
Guess it just shows that every silver lining has a cloud!
