When I was young, I wanted everything all at once

Until our old Scottish minister explained things this way:

One night he dreamed he saw a new shop on High Street.

Going in, he found an angel behind the counter.

"What did the shop sell?"

"Everything your heart desires," the angel said.

"Then I want peace on earth," cried the minister,

"And end to sorrow, famine and disaster.

"Just one moment," smiled the angel.

"You haven't quite understood."

"We don't sell fruits here, only seeds."
