I was invited to a job interview at the company where I'd be working if hired. Everything seemed fine until the interviewer, someone high in the company hierarchy, was called away before finishing the interview and asked me to wait until he got back. While he was gone I started reading the diplomas and certificates on his wall, and to my horror every other one was awarded from the Grand Poobah, or the second rank Poohbah of the KKK. He didn't come back and after ten minutes I walked out. If hired, I wouldn't have worked there.
Best wishes on the knee, Sheryl. Knees are stupid. Both of mine are borked, and have been since I was 18. I wish you better.
