Is it weird to be friends with a 16 year old?

I’m 20 years old in 2 months, and a lot of my current friends are 16 or 17 years old. I’ve never really had any friends in life. I lived with abusive parents, dropped out of middle school, and wasn’t ever allowed to leave the house. I was incredibly lonely. Last year, I decided it was time to turn this ship around and start anew, so I got out of the situation I was in, studied for the GED college placement exams, got one of the highest scores in my state, and now I’m off to college in the fall (hopefully, with the virus situation) to study for the career I’ve wanted since I was a child.

Anyways, though my sister and some coworkers, I’ve made a few friends over the last several months. I work with a lot of high schoolers at a restaurant, and my sister is a sophomore, so most of the people I’ve met are through them and they’re all 16, 17, 18. So, most of the people I hang out with are a few years younger than me. Despite the age difference, I find them relatable. We have some really academically competitive high schools in the area, and they’re all intelligent, have interests, including some shared interests, and are fun to talk to.

But, is it weird to have a friend group of 16 and 17 years old at 20?
