Our crudity rubs the English the wrong way.

Compare the American who said we were going to buy England for a summer resort with the Englishman who said that when all other entertainment in London failed, you could always listen to the Americans eat.

Crudity, "freshness" on our side, arrogance, toploftiness on theirs: such is one generalization I would have you disengage from my anecdotes.

They talk to us as they would talk to themselves.
