What's a kid's wednesday schoolday compared to work that actually matters: money to be earned, to pay bills, and get parts for breaking cars
It's just a tap, even if it did disturb the kids, they'd just roll over + go back to sleep...
See, now this makes sense. If I was the parent (and I have been) I would be leaning out asking how long he will be with the hammer, not giving him crap about how my kids are sleeping. Being a neighbour, he would know that. If I was the hammerer I would apologise and say I'd be done asap and I'll try to be as quiet as possible. This has actually happened to me. Then there would be no need for all the neighbour hatred.
