Patience with tantrums
Peter told me (at some point in the past ten years or so) that when Jay and I were kids, he used to take us to the store sometimes when he went shopping.
And he said that if one of us started throwing a tantrum inside a store, he would just take us outside, sit down with us, and wait for us to calm down. As long as it took.
I don’t remember this at all from childhood. I suspect that he wasn’t quite as patient as he made it sound. But I liked the idea of it.
