I grew up feeling very outcast. I grew up in a town of less than 50, in a super poor, rural part of the US. My interests were outdoors related, but not guns and god like everyone around me. I was more interested in learning about natural systems and the interplay of wild plants and animals and humans in the world. I never 'fit in' anywhere. None of the school clubs, none of the classes, everywhere I went I felt that I had to 'be someone else'.
Then I went to college and learned that, for many people, they literally get to do that every day, and that there was a name for it! It felt validating that someone else in the world experienced what I experienced (even if it was whole-language based instead of just dialect/cultural norm based).
Nor did I suffer abuse or humiliation from classmates or coworkers that made me change my behaviour.
