Aluminum

Not everyone knows about recycling aluminum.

Gasp.

A paraphrased conversation:

"The school is having an aluminum drive to raise money for one of the students in need."

"Oh, I just put my garbage out today. What would be involved? What would I do differently?"

"Just bring your aluminum cans to the school instead."

"What would be aluminum?"

Bites tongue.

"You know, pop cans, beer cans."

"Oh, okay."

"Not your soup cans or others like that."

"Oh, I see."

And no, this person really does not live in a cave. You'd never have thunk it if this hadn't actually transpired.
