My neighbour every time it was neighbour.
He would do things that were frankly stupid and I’d suggest perhaps do it differently.
Slug pellets didn’t kill hedgehogs and he accused me of putting a dead hedgehog in his garden.
My garden waste only bin was the cause of the rats not the birdseed he spread liberally in over his garden.
That my bins, not his very blocked drain, was the cause of the gawd awful smell and that I somehow blocked his drain with tampons and wipes even though I’m at the bottom of the ‘hill’ so my clear drains had nothing to do with his blockage. Somehow my stuff I don’t even use travelled upstream and into his loo sewer pipe to the drain 
Best one though was back when we had that really cold snap and the whole of the U.K. had snow. He decided he HAD to de ice his windscreen quickly, with hot water.
Before he poured it I told him it was stupid idea, dangerous from the splashing of boiling water, his windscreen could shatter esp if there’s dings and scratches in it and to run the car and heaters instead.
He told me to fuck off (he was a nasty harassing piece of crap, long, long story there) and proceeded with his plan.
Entire windscreen spiderwebbed and I couldn’t help but say ‘you might want to call some for that, it look real bad’ and left him to it.
He’s dead now and I miss his idiocy. despite him and his wife harassing me for years those little gems of gold star plonker lessened the day to day crap.
