"Oh, hallo, Caro darling!" Sara called. "Fancy, I haven't got scarlet fever at all-"
"No!" Caroline mocked her.
"No, it's nettle-rash. Vanessa says it's hay fever, but I know about that, and I think she means nettle-rash; she had it once just after she was married."
"I expect it's from eating all those sausages," said Caroline severely.
"Gosh, I only had about two! Or maybe three," said Sara, "and sausages never gave me anything before."
"I don't suppose you ever ate so many at one sitting before," Caroline suggested.
