Thanks for the comments, folks. Sorry, I'm only able to post erratically these days - too much to do both at work and at home.
CalamityJane: I don't think Phoebe was deliberately trying to get me into trouble (though it would've been a nice icing on the cake). Mostly, it was a power struggle. The irony of the situation is not lost on her - she was the one who had trained me on this financial application, and here I am now, correcting her errors. There are several other examples like this one that irritate ol' Pheebs. She's looked up to by the other support staff in her pool as being the 'smart' one.
dadpad: I am generally nice to people, and a good teamplayer, however, I don't go all out of my way to ingratiate myself with people. Any more. I realized that in order to befriend my new colleagues I was downplaying my own intelligence, even my personality to a certain degree; I knew if I went out all barrels tilted - they'd all get a little 'complexed' (each & everyone of them has an 'inferiority complex'). I guess I just stopped caring enough to divide and conquer, even. Take Phoebe for example. When I first started (with my New York Headquarters background/ attitude/ contacts), she was so intimidated that she always talked (to me) in this so-soft-you-could-barely-hear-her, shy little girl voice. I used to constantly have to request her to speak a little louder because she was so soft-spoken. I don't even know when that facade fell away and she transitioned to her (normal) booming voice. I realized many months later what she had done, and why. In the time in-between, I had constantly made her feel very smart (and made myself seem not so very smart while I was at it). She just grew to think (with my help) that she could treat me as a subordinate in some ways, and a not-so-very smart one at that.

Well, now. I've taken care of Most of that attitude.
These days the balance has shifted. I'm so very tired of this divaliciousness that I'm out - all barrels tilted. No more Ms. Nice Gal here - I'm all business. So, whereas before - I was not part of the Clique because I was not 'all that,' now I'm out because I'm a topic for bitching.
So. There's a new Head Honcho in the office, a new direct boss for me. Indirect for everyone else. Man, you should see the peeps all trip all over themselves, putting their best footsies forward. These sorts of things are so very telling about people.
