I lived in a long row of terrace housing, behind which ran a locked, gated alley which we all had keys to, where we all stored our wheelie bins. One day, DH lost his set of keys with the alley key attached, and at the time we were bare-arse skint and couldn't afford the £5 to replace it. They were tough times for us and we literally couldn't spare a fiver.
So we kept our wheelie bin tucked beside our bay window, at the front of our house. Technically, it wasn't 'allowed', but it was one of those things that everyone did from time to time. It wasn't an obstruction at all. We thought it would be fine until we could buy a new key (next payday, maybe)
The first week we left our bin outside our property collection, we went out to find a note attached to it, saying "KEEP ME IN THE ALLEY PLEASE" - all caps, anonymous. I chucked it away.
The next week, another note. This time saying something along the lines of, "PUT ME AWAY. THIS IS NOT ACCEPTABLE!!!" - again all caps, anonymous, the author referring to the bin in third person as though it had written the note itself
This time, I looked around to see if anyone was watching me read it. They were. A woman five doors up, standing at her front door, arms crossed and a face like thunder. I threw the note away while she watched.
Third week, and my bin had been moved to the entrance of the alley, this time the note said something like, "IF YOU LEAVE ME OUT AGAIN YOU WILL BE REPORTED AND YOUR WHEELIE BIN TAKEN FROM YOU!!!"
I was really annoyed at this point. So I put my bin back to the front of my house, went and knocked on this woman's front door, and very calmly asked her if she had a problem. She shouted and swore at me, and slammed the door in my face. She actually did report me to the council, but instead of taking my wheelie bin, they just gave me a new key and a couple of spares, so that was nice.
Anyway, this was a long way of saying that a couple of months later we were moving, and it coincided with bin day. She put her wheelie bin out and I stole it, walked it the mile or so up to the end of our very long road, and stuck a note on it that read, in all caps, "MY OWNER IS A CUNT, SAVE ME"
Still brings me joy.
