Wanting to visit a public school classroom

I'm on vacation with my family in my mom's home town. I decide I'll visit a classroom. I arrive at the school as the school day is about to begin and approach a security guard, not having formulated what I'll ask. At first, I think I'll simply ask where the homeroom for my name would be, but worrying he may think I'm a student I instead ask if I need to see the principal to get permission to sit in on a class. He directs me to the principal's office.

I explain I want to sit in on a junior high science class to another security guard in the principal's office. He tells me he doesn't think I'll be allowed because there's a lot of Tea Partiers around these days and they don't want them making trouble. He directs me to some other official who is not the principal, but in administration. This official declines my request. I think about arguing that I'm a taxpayer and have the right, but instead say I'm not a journalist but work in public relations and that this has been a very negative experience for me. I think about dropping my mother's maiden name, the family is the well respected and well known owner of a farm implement business in the small town. Instead, I tell him I want to talk to the principal. He directs me across the hall.

The reception room for the office is very lavish and modern, but nobody's there. I wander around the school, which is very modern as a whole and surprisingly large. It's lunchtime by now - the cafeteria is a large room with stadium seating. There's a special room with beds where students can take naps. I realize I'm sleepy and decide to give up and take a nap at my aunt and uncle's house.
