Another Joy of Fatherhood

So, I heard a story about a man who took his family sightseeing. They had spent most of the morning wandering about the grounds of a ruined castle. Maybe one not unlike this one. Luckily, the castle had a reasonably priced restaurant where he was able to buy the family some lunch.
Soon lunch finished and it was time for the best part of a meal with the family:
"Son do you need to use the toilet?" he asked.
"No Daddy," was, of course, the reply.
"Well, let's go anyway, just to be sure."
A reasonable tactic, no?

So,father and son head off to the WC.
Hmmmm, thinks the father, I've seen cleaner toilets in a third world bus depot.

"Okay son, let's make sure we don't touch anything in here." There, that should solve that problem, right?

So, since our hero's son is extraordinarily well behaved, things did go well. A couple of reminders "Son, don't pick that up off the floor," "Son, yes, that's just water we're stepping in, don't worry about it," were required but other than that, no problems.

Ah, success.

Sure. You'd think so.

My good friend now finishes the story about this poor man:

"Daddy, my shoelace is untied." And, yes, the shoelace was sopping.

I'm glad this story isn't about me.
