Get a load of this!
You’ve probably heard of cats bringing all sorts of treasure to their owners. It might be a dead bird, which is more of a gift than a bad omen (we think), or it might be a piece of dirty laundry for unknown reasons. In this person’s story, their cat had once given them a dirty sock out of nowhere, and in response, the owner showed affection to it.
This was the start of a weird cycle where the cat would bring over dirty socks to the OP at random times and expect praise for its effort. At least the stuff the cat brings is the OP’s dirty laundry and not those belonging to the next-door neighbors (we think).
