Ouuuuuu yeah - I know that one...
In that context - yup.
I had a boss once that would get insecure when I excelled so she would have to add her two cents to what ever I had done (usually in front of clients, especially if they liked what I was doing) and always started the sentence with "For your edification..."
I find that people that always talk about the importance of "communication", "team playing" and "problem solving" are usually the worse offenders of doing just the opposite of what they are preaching.
"Slippery slope" rubs me wrong often as well.
That said, in general I think people should talk less and do more.
