Just wondering what you would do...
We get on quite well with our neighbours and our gardens have a fence in between. Their twins are 9 and often have friends round and kick balls around on their garden.
When we first moved in the kids would knock on the door to ask if they could get their ball back and I said there was no need to ask (as they were waking DS up when he was sleeping).
But now they routinely kicks balls deliberately into our garden and crawl through the fence and almost play volleyball over the fence!
I know it's not a big deal but it gets irritating after a while. What would you do?
