here's one of my favorite Dad things i've always done with my kids. since they were toddlers, i would take them to the grocery store with me, usually every week (this was before covid, so I didn't have to worry about masks and such). they'd sit in the shopping cart, of course.
when we got back to the car, they'd still be sitting in the cart while i unloaded into the car. when i was just done loading, i'd check around surreptitiously to make sure nobody was coming and then "accidentally" bump the cart, making it slowly roll away
then they'd start hollerin at me and i'd turn around and pretend to be surprised and run after and catch them. pulled that again today with my 5yo and he absolutely lost his business laughing
