I used to have a self-loathing dishwasher. Swear to god. It started into the first cycle fine, then churned slower and slower, then emit a long, baleful groan, then stop with a loud clunk. Then it would tick… tick…. tick… for a few minutes and suddenly the spray would start up exuberantly, like it decided that it wasn’t going to allow it’s world dirty dishes beat it down. Lemons to lemonade. But soon it would get weaker and quieter until all you could hear was the sad rain at it bottom, then it would clunk to a full stop one last time. It actually sounded depressed. After that, it would let out little moans at odd intervals all night long unless I mercifully pulled the plug in an act of euthanasia.
Really freaked my cat out.
