They moved next door 2 months ago. They have a few children and pretty much every day since there has been something new in my garden. First it started as balls and I just threw them back. Then half an hour later they are back over the fence. But now it’s other things. Small children’s toys, a doll, a single child’s shoe and today a plastic takeaway container that still had dried food in. I would say out of the 2 months only 2 days there hasnt been anything come over. I also found a cigarette end at the end of our shared drive way chucked over on to my side and a melted cream egg that they’d left. Would you say something as it’s starting to get annoying now
