No! -- at least, that's not what's suggested in the (excellent) course which DanBC linked to. An eye opener for me! Don't divert the focus to others. And (this is my take) don't be talking about what the person mustn't do -- they already feel boxed in! The goal is to steer toward a positive outcome. The course deals with this (and other) points better than I can. Recommended!
