I basically said I am over it. I also said I doubt the team has forgiven him. I doubt that explanation was enough of mea culpa to satisfy anyone. I hope he has addressed the team on his own. Even if he has, it still may not be enough. I have been part of numerous close knit units. When someone quits on you like that, it takes a lot more than a few days to forgive and even longer to forget. Maybe you are right, but then again, based on my experience on teams in the past, you are probably wrong.
I will add, it is one thing to quit and take yourself out of the game. It is another thing to quit on the field in such a way that you basically force the entire team to quit along with you.
It is bad enough if we are in a foxhole together and you run away, leaving me alone, yelling, "We cannot win!" It is much, much worse for you to yell out, "We cannot win!" as you blow yourself, and the rest of entire squad, up.
