即使要说，也必须出于善意，方式得体，如：
先把方案B准备好，也就是您有补救措施；然后，机会得当的时候，有如下这样的对话：
Boss: Anything else to talk about?
Guy: Yeah, I got something bizzar, would you want to look into it?
......
Boss: Ahhh, I got it. Looks we're in trouble, what should we do?
Guy: Well, not that big trouble -- I have been having second opinion, and have put something in reservation....Blah blah -- describing plan B....
相信这个世界，能处理敏感问题的是大本事，会有回报的！
