I work with eight other teachers. Two are dudes, six are girls. Aside from one of the guys (who's a bit older), everyone is in their mid-twenties. I'm the second-youngest person.
The co-worker situation is as good as I could have hoped. Everyone has been really supportive. Whenever I have a question (all the fucking time), they generously pause their day to answer it. We hang out on weekends. It's a really solid crew.
