I don't suppose any of us have the right to peace and quiet, but you normally find with lawnmowers, petrol hedgetrimmers, kids, fires etc. that yours are slightly less annoying than other peoples'. There is some headland at our site that where the children normally play and I often mow it for them. It always helps if they have a bit of land to work/play on. My young ones are still sometimes tediously noisy though!
I try to be both tolerant and considerate -which is a Zen character improving challenge for me as I was born cynical and grumpy. However, I think my elastic limit would be stretched if my crops or equipment were damaged. It is a serious responsibility to teach your children respect and whilst accidents happen, and a note shows admirable honesty- it is not enough; you should expect an offer to help fix the damage. You are definitely going to confront them and discover their real attitude now.
What I am trying to say is: You can not carry on having them interfere with other plots but I hope you will be able to start an improved relationship rather than descending to acrimony. I don't think getting cross and bickering or driving them off will teach the kids anything positive.
