What wonderful things you are learning! I'm glad you finally have a T who listens and "backs up" and looks at things again, "engages" with you in figuring out what to discuss and can admit to being wrong when he is. That is great.

Bravo for being so brave and sticking to your guns too. That's how I learned "anger" wouldn't demolish me, when a boss got angry and wouldn't listen and I knew I was right and kept insisting/telling the truth until he heard me.
