I remember going to the circus in a huge arena as a kid and loving the elephants, being vaguely annoyed by the slapstick clown act that never seemed to end, and being utterly entranced by the acrobats. Flying through the air and landing in a giant net looked wonderful.
I also remember the souvenir hawkers walking up and down the aisles selling, of all things, chameleons in plastic cages, which I was told I couldn’t buy because they would die.
