Exactly my experience Dora. Mike gave me a hard time about vnav on the -400. Funny thing was, he was wrong. After a good natured argument, he started laughing, patted me on the shoulder and apologised, admitting he was wrong and commending me for fighting my corner. You are correct, friend for life after that. He was right far more than he was wrong, and expected a high standard. I don't see a problem. He also came from a background that didn't tolerate 'precious' personalities, and those that couldn't accept criticism and correction. He is a good man, and it's pathetic and disappointing that there are those out there who feel it appropriate to kick someone anonymously, without considering the whole person. He endured much more than most these past few years (personal family tragedy and health), and I can only wish him and his family the very best for the future.
