Someone who has been alive for 12 years. A lot of people associate 12 year old with that one kid who picks his nose and while playing fortnite. That’s not all of them. Many 12 year olds are actually pretty chill, and even if some are hyper, you don’t gotta hang out with them, just don’t insult them. This is coming from a person who is 12 and has ADHD. I don’t mess up the class, I try to keep it in as best as I can. In my grade, where everyone is 12 or 13, people usually keep to themselves and don’t disrupt everything.
