Thanks, all. I was really shaken up by his "I can't be there." Really, the selfishness of bringing all this drama to a nice woman who is doing her best to direct a show for the first time.
I will have to be the better person with this. Be flexible, be calm, if I am needed to leave so X can do his lighting work, fine. I will graciously go so the director can have him do the work necessary.
But I also have to fill my responsibilities to the show, and that doesn't always mean I conveniently disappear when the lighting guy shows up. Sheesh...
