When my children were toddlers we lived close to the dead end of a close of terraced houses. One family who, I suppose people would describe as rough, they kept a fast food van on their very short drive, had a tribe of secondary aged sones who regularly played football at the end of the close, running all over peoples front gardens, and in my case, damaging some rosebushes I had planted. They got regular flak from others in the close and I was none too pleased about it either.
One day I went out, not to complain but to ask them, when the ball landed in my pocket handkerchief front garden, whether they would just come and pick it up and not kick it through the roses. They were cheeky to me, so I said if they were so difficult, I would speak to their parents. They thought this was a joke and 'dared' me to. So I walked up to their front door and rang the bell, when the father came to the door I said I wanted to talk to him about the football and all the children piled in expecting me to be bawled out.
Instead I sat down and told them I could understand their problem with so many children in the house and a tiny back garden, and no nearby park, so the boys had only the close to kick a football around. I then said, my problem was not to stop them playing football, but just to ask that if the ball landed in my front garden they should lift it off the grass and not kick it until it was back on the road, but also to try not to get it on my garden.
They were so gobsmacked, that I was so nice to them and my request was so reasonable, they agreed and the boys heard their father agree and we parted on the best of terms. And after that the boys did stop kicking the ball off (and frequently onto) my grass and I remained on the best of terms with the family.
Many nasty obstreperous people are like that because people treat them badly. Be nice to them and it is surprising how accommodating they will be, simply because , for once, instead of shouting at them, someone has been nice.
