DP's last flat share before moving in with me. Angry phone calls at 7am wanting to know why he'd used somebody's hairbrush as it was full of brown hair. DP's bald. The kitchen was unusable as every surface had cans, bottles and packaging welded to it with a thick layer of grease.
One turned out to be a heroin addict, so he had to lock his bedroom door every time he went to the toilet.
A new person moved into the living room and decided he wanted a bedroom, so DP caught him breaking into his room to chuck his stuff out (whilst addict hovered so he could 'take care' of the stuff that had a resale value).
DP decided 'fuck this' and gave notice on his room. As soon as the new person found out, he smashed his way in and threw DP's remaining stuff out of the window whilst he was at work and his mate had moved into the living room by 6pm. There was still three months left on the contract, so he thought 'bollocks', and got the landlord to agree to terminate his contract with immediate effect, rather than put them through the obligation to get the 'new' person in his room out, plus the new one in the living room, only for him to leave again immediately afterwards. Got it in writing, too, confirming he had no further legal or financial obligations in respect of the property.
Nine months later, he was getting hassled for money by them by phone & in the street as he walked past to go to work. Turns out that they had decided the electricity, gas, TV licence, broadband and council tax bills weren't their responsibility, they were DP's as he'd been the oldest person there by two years, so hadn't paid a penny since he'd moved out.
DP was registered for and paying council tax with me for the entire period they were claiming he hadn't paid. When he said 'No, I'm not living there' and provided evidence to the council and other creditors that he wasn't there and had been living with me, they went on a social media binge of claiming he'd stolen from them.
You can see the roof of the flat from my bathroom window. Just before he moved out, DP had noticed some tiles had fallen off and mentioned it to the others, but didn't tell the landlord that was probably why there was a large damp patch on the kitchen ceiling, as he just wanted his letter and out.
The kitchen ceiling collapsed a couple of months (and big storms) later. They didn't tell the landlord for another six weeks. And then claimed that DP was supposed to do it - when he'd officially moved out nearly a year before.
