My mom made us all repeat the rules before we left the car (no running, no putting things in the cart without being asked, keep one hand on the cart while we are moving or something like those)

Wow, I’d forgotten this till just now - my mother did the same. Thanks for the memory jog!

I can remember being 2 or 3 years old and the golden rule then was to always be holding someone’s hand - parent/sibling, etc.
