I treated it like a job. Showed up, put in my hours, didn't really engage with anyone. I had a lot of friends much older than me at the time. Just wasn't too concerned with the social politics of high school. I probably had more goings on with the administration than I did the student body.
My accent is probably a bit spotty. I've practically lived my whole life in western Kentucky. Some words like "lawyer" come out country as hell. Other words like "tire" or "wash" I've actively worked to pronounce properly.
