In my case tonight, it was an utter and complete accident but still my fault - I made plans to take my SO on a date. I stretched out on the couch for a wink and set my alarm because I was feeling a bit tired, but accidentally hit it off instead of the snooze. Low and behold I slept an hour beyond when I was supposed to take my s/o out and I woke up to find them in their pyjamas despite it being early still. I was apologetic and extremely upset at myself and still said that I wanted to take them out as promised and I was already ready but they said they were already ready for bed and angry with me. Cue the silent treatment. They didn’t try to wake me up, not that it was their responsibility, but what was supposed to be a fun night was ruined.
