The principal called me tonight to tell me that I did a great job and my lesson was excellent, but that they had to go with someone else. She did say that she would give my name to the other administrators in the district. She sounded oddly dejected and unlike her tone in the interviews, which was weird. I didn't probe about the whys, I just said thanks and tried to be as gracious as possible. Maybe I should have pressed her. I did get called for an interview in another district on Friday. So at least there's that.
