We have dreadful neighbours - loud, unpleasant and rude. We are quiet at home and don't give them any bother at all. We don't complain when they come home late most Sundays and blast their music until the wee small hours, or when they flick their fag butts straight out their side window downstairs and they land on our path. We are just 2 hard working people who just want a quiet life really and have decided just to smile and nod when we see them and leave it at that. The fence panels between our gardens are our responsibility. When they collapsed in the wind at Easter, we decided to have a wall built, which cost quite a lot of money. It has given us a bit more privacy in the back garden. Imagine my horror as I was cooking dinner when I saw 8 or 9 year old son of neighbour, who doesn't live with the mum but visits every other weekend, sitting on the top of the wall and climbing into our garden. My husband was calmer than me and went out and asked him to go back to his own garden and let him out the back gate. I am annoyed that our defences have been broken and would like to do the old fashioned placing of broken glass on top of said wall, as my granny would have done, but of course I can't. Anyone got any ( sensible! ) ideas of how we can stop this. Talking to the nutty neighbours won't help, as they were in the garden this evening and were laughing at the lad. Help!!
