The lesson didn't go well and my observer made it a point to let me know how miserably I failed. I have gotten critiques before, but this one was different. I felt like a failure. My observer had not liked one thing I did in my lesson. I felt as if I wasn't a good teacher. No teacher likes that feeling.
