I should have realized, being a NEGOTIATION seminar, I might be expected to speak and, well, practice negotiating. Which is exactly what happened. I had to talk - and talk a lot. So much for an effortless legit 8 non-billable hours.
What all this talking helped me realize was, no matter how much of a push-over I think I am, I can actually be a mean girl when it comes to bargaining. In one of the exercises, one girl said I got what I wanted because I lied (gasp!), when in truth I was just bluffing a little (I think).
Lesson for today: Hooray! I can be a bi-atch!
