Question: Call me naive, but I don't get the "Mile High Club". Anyone care to explain?
Question: What is the story behind Grizabella? Why do the other cats seem to hate her and shun her?
Answer: It's a bit vague, but when Grizabella was young, she left the other Jellicle cats, turning her back on them to live another life, thinking she was more glamorous than the others. Now that she is older and has fallen on hard times, she returns, wanting to rejoin the tribe. The other cats are resentful that she considered herself better than them, and they are put off by her shabby appearance, so do not want her back.
Answer: "Mile High Club" refers to people/couples that have had sex on an airplane (most commonly in the tiny airplane bathrooms).
