carbon copy
If you are cc'd, it means you are copied, as in for your information. You are not being questioned, noone is asking you to do anything other than be informed by the email. Therefore, to act as though the email was to you and only you is ridiculous. To respond as though someone is asking you what to do, rather than the people who were actually in the to: field of the email is not required. If you were cc'd, its because I was trying to be helpful to you in doing your job, not because I was asking you to do mine. As you are a coworker, and we are both working on the behalf of the same goals, we are part of a team and when I include you on information, it is because it is in the best interest of completing our goals for this job. It is certainly not an invitation for you to judge what you perceive as weaknesses in my personality and forward that to my boss. You do not know me well enough to make that judgement. I do not decide you are an a*#@#$* based on one of your email responses, I kindly request the same.

sometimes you just have to say WTF but noone is around to listen...
Therefore...
WTF?!?!?!?!

Words of the day:
Expiation - from the freedictionary.com "compensation for a wrong" is the first more useful definition. Also, it is what spell checker does not catch when the word meant to be there is "expiration". So I had to see what it must be.

Fiduciary - I had to look it up because its one of those funny wrong sounding words, that when I heard it, it sounded like it had to be a mistake. Look it up, its definition is much more boring than it sounds.
