Have lived in current house 15 yrs and always had a good, not close, relationship with neighbours. We very recently agreed to go halves on a fence between our back gardens as the previous one was rotten and about to collapse and had loads of ivy coming over from their side to ours. The team did a great job, took our a few trees and v larger ivy roots. The other day I noticed neighbour had a hose/sprinkler pointed at fence right by my back door so they're not really watering flowers (think he grows sunflowers there) but watering the entire 6ft fence and water seeping all the way through and also my plants and paving (and me if I walk out the door). I texted owner's son (also living there and my contact for them) and he said he'd ask his dad's to stop but gave a shirty reply about "sorry if he's not watering correctly". I said it's not about watering correctly just don't want new fence to go rotten like old one. Anyhow 2 days go by and no more watering of fence (something I admit he's done the last 15 yrs which has always bugged me). I've gone outside just now and it's midnight and he's watering the fence again- presumably assuming i wouldn't be out this late. I really am pissed off as I know it will ruin new fence and is really pointless. He's only got concrete breeze blocks with weeds and a few sunflowers. I don't want to seem rude- parents are elderly and have always been nice but given I've just paid for the fence I feel I should stand firm. AIBU?
