For example, in r/pettyrevenge, there is currently a post where a woman, a teacher, is boasting about how she got revenge on a friend in kindergarten. Kindergarten! Bragging about something she did in kindergarten?! A whole lot of her posts are bragging about things she did when she was a kid. This isn't the first time I've noticed this either. Maybe it's just because I don't remember much of my childhood, but I would never ever talk about something that happened in kindergarten as if it mattered at all. Is it because they totally lack accomplishments otherwise? I just don't get it at all.
