HA! I told one of my ex's to not text me at work. She did it all the time anyways. By boss was an asshole. So on friday saturday night I'd text her late. I broke up with her because she would constantly talk about her ex. I told her to fuck Sean and leave me alone. Done. Deleted her number.
Few years later, I was in a hotel. Had the phone in my pocket. It showed I had a missed call. Pocket call. I didn't know the number, but it showed I recieved some messages from this person previous. Didn't put 2+2 together right away. I got a lot of lovely voice messages after that!
