I remember the time, when DS was about 3 years old, we lost him in a mall. Of course we hunted then called the police, and he got everyone involved. A clerk from a book store strolled over and asked if we were hunting for a little red headed kid, he had one who was reading a book, Hop on Pop, comfortably settled under a sales table!!
I didn't know if I wanted to kiss him or spank him first!!! After that, I got a harness for him and he stayed close to us till he learned to obey the rules.
