A Parable about Keeping an Eye on the Kids

One way John would often help me when the boys were younger would be to take one of them with him while he was running errands; as any mother knows, little boys (maybe girls are the same but I guess I won't know for sure) love to egg each other on, especially little boys like mine who have very different interests.  My husband loves to read, loves buying books, looking at books, collecting books, et cetera, and many times stops in at the local Parable Bible Bookstore to peruse the shelves. 
When Zach was three and freshly potty trained, John was out with him and decided to stop in at this particular store; the ladies there are very sweet but mostly a bit older, giving the impression that they have forgotten what small boys are like - it was my own personal nightmare to take them into the Bible bookstore due to the numerous glass figurines placed on low shelves all throughout the building.  However, where books are concerned John is fearless, so in he and Zach went.
John ushered Zach over to the children's play area, where a veggietales movie was playing and a table of giant legos waited to be played with.  As he was skimming over a book, one of the sales ladies  came over with a small smile.
"Isn't he cute?" she said, gesturing to Zach.
"Mm Hmmm, " my vigilant husband replied, politely glancing up before returning to his book.
"Yes, he's really something." She kept the conversation going, waiting for John to reply.  He finally got the hint and lowered the book, only to see his son racing around the store, completely naked from the waist down.
