Great way to say it, William: "Leadership... is a philosophy of human interaction that acts as a social lubricant."

Yes, people are often promoted as managers without having developed the leadership skills.  And I think sometimes we use the terms casually and interchangeably when they are not.  I think that is one aspect that got "lost in translation" between me and my instructor.  And still, her response made me think.

Thanks for taking the time to respond.  Mary
