"I'd rather surprise you."
"So I gathered. Why did you change your suit?"
"Change my suit?"

"I haven't changed my suit."
"Well! I suppose that's the one you were wearing before."
"Look, Tinker, I don't usually wear a suit for three months. I think it was about time I changed. In fact, this one is about done for."
"The one you had on before looked all right to me."
"So? How long do you expect a suit to last, anyway?"
