I was oh so tempted to do so this morning. That's after having had to endure an entire afternoon and evening yesterday of children next door screaming and shouting in the garden, parents totally oblivious, letting their kids argue and throw tantrums. It ruined any chance of us enjoying our garden and ended up having to go inside just so we didn't end up totally stress and shouting things at them.
So yes, giving them a bit of their own medicine would have been satisfying, but I can't get myself to fall into a war of disturbance. I'm sure this afternoon will be just as bad and once again, we will have to forfeit enjoying our own garden.
Could it be that your neighbour is passing on a message by doing it? I bet if I had done so, my neighbour would have been oblivious to why I was being so unconsiderate because they clearly don't care at all that their kids are a complete nuisance.
