Pre Adult Teenagers can prematurely age adults.
It seemed weird calling a teenager 'sir' but I'd learned to be careful with immortals. They tended to get offended easily. Then, they blew stuff up.
I walk around the school hallways and look at the people. I look at the teachers and wonder why they're here. If they like their jobs. Or us. And I wonder how smart they were when they were fifteen. Not in a mean way. In a curious way. It's like looking at all the students and wondering who's had their heart broken that day, and how they are able to cope with having three quizzes and a book report due on top of that. Or wondering who did the heart breaking. And wondering why.
