I'll take it as I didn't hear you.

John and Jack met in the street one day. "I want to ask you a favor, but can you keep it secret for me?" said John.
"Certainly I can, " answered Jack.
"I'm short of money these days. Will you please lend me some?"
"Oh, don't worry," Jack said. "I'll take it as if I did not hear you."
一天，约翰和杰克在街上相遇。约翰说：“我想请你帮个忙，
不过你能替我保密吗？”
“当然能。”
“这些日子我缺钱话，你能借我可以吗？”
“噢，别担心，”杰克说，“我就当没有听你说过。”
