Make it nine months

"Mr. Clark, I'm afraid I have bad news," the doctor told his patient. "You only have six months to live."The man sat in stunned silence for the next several minutes."I can't possibly pay you in that time.""Okay," the doctor said, "let's make it nine months."

九个月吧

“克拉克先生，有个坏消息，你只有六个月可活了。”医生告诉他的病人。病人惊呆了。“六个月我不可能付清医疗费。”“好吧，”医生说，“那就九个月吧。”

He would better pay the doctor in as long time as possible.

I would run off and not pay the doctor at all.
