The Adventures of Sally by P. G. Wodehouse

Mr. Carmyle was not a man who readily allowed himself to be disturbed by life's little surprises, but at the present moment he could not help feeling slightly dazed. He recognized Sally now as the French girl who had attracted his cousin Lancelot's notice on the beach. At least he had assumed that she was French, and it was startling to be addressed by her now in fluent English. How had she suddenly acquired this gift of tongues? And how on earth had she had time since yesterday, when he had been a total stranger to her, to become sufficiently intimate with Cousin Lancelot to be sprinting with him down station platforms and addressing him out of railway-carriage windows as Ginger? Bruce Carmyle was aware that most members of that subspecies of humanity, his cousin's personal friends, called him by that familiar -- and, so Carmyle held, vulgar -- nickname: but how had this girl got hold of it?

If Sally had been less pretty, Mr. Carmyle would undoubtedly have looked disapprovingly at her, for she had given his rather rigid sense of the proprieties a nasty jar. But as, panting and flushed from her run, she was prettier than any girl he had yet met, he contrived to smile.
