When I was a kid, there was a Gifted And Talented Children program (or something like that) and a bunch of smart kids were invited to come to the Museum of Science on a day when it was closed so that we could listen to lectures about being smart and eat crappy box lunches. I brought my best friend along.
We skipped out of the lectures and went nuts in the empty Museum of Science. It was ours, all ours. We went down back stairwells and found empty corridors and saw disused corners with forgotten display cases that no one had looked at in years. We got to peek into the box rooms and junk drawers of the house of knowledge. Delight! And we didn't get caught!
I wanted to see places I'd never seen before. I wanted to learn secrets.
My friend just wanted to go to the tops of the stairwells and spit down the middle.
