Let's go to the fair!

Going to the fair with kids is always a challenge depending on their ages.  Little ones can be put on a leash and guided around.  Once they hit a certain age you can't, so you must grow eyes to watch them.  Why does each child want to go in a different direction?  We need to stay together.  To them that means wherever they want to go you will follow.  Bobby was the one we always kept an extra eye on.  He liked to wander more than everyone else.  He never looked to see where anyone else was.  On occasion he would disappear and we would be frantic, of course he was looking at something and enjoying himself.  Now that he has his own kids he often wonders how we did it.  I just tell him all my grey hairs have a name, and he caused a lot of them....
