A few weeks removed from dealing with said person in, well, person, and some time after having the last e-mail exchange with that manager (even those e-mails, by the way, would make me tense: Uh-oh, what will [this person] be on about now?), I've decided to mentally move those thoughts for that proposed long, long post to the Trash Bin. Because this person is not a factor in my life anymore. That's a better thought than any kind of venting I'd do.
So deletion starts...NOW. (Hey, I didn't say I could let go immediately. I can dwell, y'know? Stopping the dwelling might take a bit...)
