Some of the stuff posted online is meant to teach us a lesson, and these "educational" posts tend to make the poster sound egotistical and smug.
But Redditor Msmessyclean wasn't trying to stroke her own ego when she posted eight screenshots of texts she received from an overeager fellow after cancelling their date- she was trying to teach people what not to do when someone cancels a date.
Msmessyclean says she thought similar stories of crazy guys going too far were "rare and exaggerated", but when it happened to her she felt like sharing because "it's important that people are aware of this kind of behavior and go with their instinct if they sense something is wrong or off."
This guy seems like the living embodiment of "off"!
