Neighbours are a lottery, and how I wish you could ask for references for them before buying a house close to them!
We have 6 houses close to us, the occupants of 5 of them are lovely, helpful, and we have drinks together,and help each other out when away. The occupants of the last house, which has an outbuilding making up part of our boundary wall, have fallen out with four of the others, but until now had left us alone.
They recently posted a multipage nasty aggressive letter through our letterbox telling us we had three weeks to move our shed and patio away from their wall, we are not to put plants on our patio because watering them might splash their wall, our tree roots are uprooting their drive (they aren't, and anyway the drive belongs to another lovely neighbour we would be happy to work with if that were the case) etc etc. My husband is sick with worry and can't sleep, doesn't want to walk out of the house in case he sees them. We have gritted our teeth and written a friendly reply offering to do some small things to please him and share the cost, but he will be back, we know they never give up once they have a set idea in their heads, both of them will go off on a rant at the slightest excuse, so not a case of calling round with a cake as peace offering!
