My wife observed the following scene:

A granddad was waiting outside a trinket shop. His grandson, about 8 years old, came out and said, “Why aren’t you in the shop with mum and nan?” To which the granddad replied, “I’d die before you’d catch me in a shop like that lad.” Then the granddad put his hands in his pockets and strolled in a circle. The grandson, watching his granddad carefully, put his hands in his pockets and did the same.

This scene speaks volumes about the influence of adults on children. This vignette can be both an encouragement and warning. Our example determines which.
