I grew up in a small town and went to a small school. My graduating class was 72 people. I graduated in 2009 so some of the things that occurred in my school were not PC.
A lot of previous posts were on point: The jock, the hot chick, nerds, theatre kids--all the cliques. However, it's not what the movies make it out to be. Everyone has their group they flock to, but everyone was polite to everyone. Everyone got along for the most part. It was simple country etiquette to be polite to each other. Even handicapped kids weren't targets, they were treated equally like everyone else.
Fundraising, sports, dances, decorating the halls, were INSANELY popular things to do. Being active in extracurricular activities was the norm that EVERYONE did, even the recluse high school kids. This is because there's nothing else to do, so everyone is very active in school.
Not much of diversity in ethnicities or other religions.A lot of folks were Christian. You wouldn't be targeted if you didn't follow Christianity and they certainly wouldn't try to convert you, but you would've been part of the 0.1%
Everyone was having sexual intercourse everywhere. Janitors closet, storage rooms, baseball dugouts--you name it.
Everyone got their licenses as early as possible. This is because a lot of people lived on farms so they drove to school a lot. For those of us who lived in the small town, we walked to school.
In my middle school, lunch,recess, and reading all happened in less than an hour. We would have lunch for 15 minutes, then recess for 15 minutes, then reading session for 15 minutes. Then it would rotate each day. In high school we had open campus lunch--which means we had the choice to eat wherever we wanted. Some people ate in the cafeteria (which was VERY TINY like only 5 tables fit in there), some kids ate in the schools library, hallways, fields. Or we would walk to the gas station or eat at home or drive 20 minutes to the bigger town and get fast food there.
A lot of teachers allowed food and drinks in their classes, and graded more on participation in class rather than grading on homework (we still got homework, but our teachers encouraged us if we wanted a better grade then we needed to be more active in the classroom discussions).
A lot of people got jobs at an early age. Most kids earned money to go to camps, buying things, etc...working on farms in the summer. Heck, I started babysitting when I was 9 to start earning money. Then I did odd jobs of working on farms and around the small town. I got my first official job at a bank when I was 16.
Rumors spread like WILDFIRE. Since everyone knew everyone, if there was one rumor started in high school you can bet the rest of the town would know about it by the end of the day.
Sports games and tournaments were something that EVERYONE in town attended. If you want to get the whole town in one spot for one night, just go to a football game. Tractor-pull events also happened every summer.
A lot of people in high school were related. it was very common to see groups of cousins, siblings, you name it.
A lot of people wore cowboy boots, it was considered fashionable. Rich kids wore them the most. Most of the rich kids, their families owned wineries.
There was practically no LGBTQ+ community. When I attended high school, I only knew of 4. Myself included. When I came out just as bisexual, I was targeted for bullying. I got death threats in my locker and death threat phone calls at my house. This also spread to the entire town too, so even people at the gas station would look at me with disdain. I also had no friends for an entire year as no one wanted to talk to me. However, once the new school year came around so did people so there's that. But from what I've heard, the town has improved their view on the LGBTQ+ community so it's willing to accept change.
EDIT: Forgot really quick. Every year there was a Senior Parade. This was for the graduating high school seniors. We usually decorated a farm truck that pulled a trailer. It was loaded with hay bales and it would be decorated with our school colors. We would also dress in our school colors. This was something ALL senior students participated it, didn't matter what background you came from.
The popular/rich kids would ride in the bed of the truck or on the trailer. However, most country boys were polite so they would try to get all the girls on the trailer so we would have some place to sit while the guys would walk. We would parade our "float" around the town and everyone would come out of their houses/stores to wave and congratulate us.
(sorry for the novel. I think that's all I can think of lmao)
