I have another one. Same son, same age.
We were in a Hughes lumber shopping. While going down the aisles I paid more attention to what I was looking for than his location as he never left my side. When I looked around and didn't see him, I panic'd, and starting rushing down the aisles looking for him.
Finally found him with his training pants down around his ankles, peeing into a display toilet. Pulled his pants up, quietly praised him, and left the store quickly.....
I know, should have offered to clean it up, but was so embarassed at the time.
Man Dennis, I am never coming anywhere in public with you and your kids! Geez....... I thought mine were bad! Control your kids man!!!
