Mallyh,you are worrying about upsetting the new neighbours and bad vibes, well, as i see it, they are new in your life, you were there the whole time and it is them that should be worrying about upsetting the neighbours - some ground rules need to be establised or next they might be bringing oul bangers of cars up and leaving bits of wheels and heaven knows what around. They don't care about any of you by what I have read, I would not send anonymous videos to the council, but i would tell the newbies, you have been cleaning up their pets poo and it's unfair, you have it on video and if they don't get their act together you will pass the footage on to the council, are they renting? new buyers, renting from a private landlord, if it is the latter, tell them you will be having words with the landlord - I would be furious, you are a very calm couple to let them away with that and it leads to bad health too, stress and all that kind of thing, get it sorted before they walk all over the neighbourhood
