I was pretty popular in elementary school.
I remember always being accused of being "shy" - I wasn't actually shy or afraid, but small talk just didn't come naturally to me and I wasn't interested in useless banter, same as now. Adults would often say i was shy, but I didn't feel hindered by it.
I was pretty smart and I was popular among the teachers - at the time, it was cool to be friends with teachers and people liked the smart kid. I also had specific interests in common with my friends: animals, specific online games and trading card games, drawing, writing stories. I was clever and organized, so I was usually very good at the video games, very knowledgable about the tips and secrets, my card collections were extensive and orderly, etc, and this attracted people.
Relationships got more complicated in middle school and my popularly died out, but in high school, I started taking classes at the community college and found that I got along with the older crowd much better than my teenage peers!
