The mystery man on the motorcycle is grandson Michael.  Wow!  I remember the days when I was younger, living in Singapore,  riding a motorcycle.  Michael's Grandpa Gary and I owned a motorcycle together in those days.  Today was a reminder of times past.  This guy is all right and a joy.  Of course, I had to tell him the scary stories... and told him how to be safe... and I knew he knew already, but I had to say it.  He knows me well and could tell that I was full of envy... and pride in him.
