But she never could fathom even going to a restaurant to order a lobster - and that some people thought it was fancy would make her head explode

This makes me think of how shredded tuna has become very expensive during my lifetime. It's still not super expensive but it's not dirt cheap either.

I'm thinking that when I'm old, will I see fancy restaurants serving spaghetti with shredded tuna, accompanied with real parmesan.

As it used to cost like some cents or something. Like 60 cents € or something for a can, whereas now it's more than 2€.

Hehe, sea bugs.
