George was a pirate, but he wasn’t a very good pirate.
The captain constantly shouted at George, making an example of George for the others.
“YOU’RE NOT A VERY GOOD PIRATE! WHY CAN’T YOU BE A GOOD PIRATE?”
When he was just getting his sea legs, he wasn’t very good.
But with time and experience, he got better.
It was the captain who wasn’t a very good pirate. Or a very good leader.
George looked at the crew and wondered who would make a good replacement captain.
Then he looked in his mop bucket, saw his reflection, and pondered mutiny.
