Don't feel bad about hanging your washing out. You've got to do, what you've got to do!
But I'll share my pain from the other side...😁
Our houses are mirror images, unfortunately this means the neighbours front door is inches away from my kitchen window (no fence, can't have one).
They have one of those ghastly (door curtains?) plastic things you hang in the doorway to try stop flies going in the house & prevent people being able to see in so easily.
They have it on the outside of the door so it's there 24/7 flapping about. Being right next to my kitchen window, the flapping drives me batshit & the waving about at my kitchen window is very, very, bloody annoying, I keep thinking someone is stood there!
However, I've had to resign myself to putting up with it because I can't think of a way to ask them to remove it when it's not in use (ie their door is closed) that doesn't make me sound as fucking batshit as your neighbour 😁😁😁
Then there's their washing. Rotary line, casts a lovely big shadow over my patio & there's washing out there pretty much 24/7, 365, because they seem not to bring any in until they need the space on the line to hang more out? It's weird. They're weird. Thankfully they're really nice too.
