My darling father, who is a genius in so many ways, has a harder time understanding theatre than almost anyone else that I've met. I've been explaining things to him for over 10 years now, and still he occasionally asks, "Okay. So what's the difference between the lighting designer and all the other designers again?" I don't really know what to do with him.
Every time I see him, he asks me whether or not I've become a director yet. When I tell him that I don't WANT to be a director, I'm a stage manager and a board programmer (lighting and projections), he is completely bewildered. In his mind, the director is the very top of the food chain, and the ultimate goal of everyone in theatre is to become one. I think the reason for this is twofold. First, the movie world teaches us that the "best" people (the ones whose names everyone knows) are the actors and big-time directors. The director is "the boss". Second, my dad is a Lt. Col in the army, so his world is very hierarchical - he doesn't seem to comprehend the idea that in theatre, one designer isn't necessarily better than another, and the director isn't the top rung on the ladder.
Similarly, he frequently asks, "So why aren't you working on Broadway yet?" To him, Broadway is the ultimate goal for theatre folk, and since he accepts nothing less than "the best" from his daughter, every year I spend not on Broadway is another year I've failed to really succeed. *sigh* I may someday go to Broadway for the experience if the right opportunity pops up (and who knows? maybe I'll love it), but I don't think that it's for me! I love regional theatre and at the moment, see myself doing it forever.
