Another child might keep doing that or do it to other cars too. You had a well behaved child regardless of this one action. Some children are not well behaved
I know especially in the USA we want to talk about "what people deserve" rather than "what works" (vaccines and general covid response anyone? like we'd rather have someone to blame and have the right people have bad outcomes we think they deserve, than actually do things that work?), but what a mess.
Of course, that does not mean it's a good thing that some humans destroy property and make other people's lives miserable, but it's nice to know that the indomitable still exists within us.
