If I were you, I would go. People know that artists frequently are "eccentric," so they tolerate "difference" more. You can also explain the process through which your art was created. Or maybe, if in a particularly expansive mood, state a "manifesto." Perhaps you could write out a "manifesto" to give out to people.
You can make good artistic friends through these "closings." You might even get good wine and cheese out of them--and, in rare cases, actual good food.
