Duffy is not luggage

"Why is this luggage behind a fence?" asked Duffy.

"Be careful, or you might get taken on board as luggage," I said.

"Well, that wouldn't be so bad," said Duffy.

Then we saw the train.

"What do you mean, they strap luggage to the top of the train?!"

I thought it looked cool. Fortunately, Duffy is not luggage.
