I like to do this really mean thing to actors in which I make them be ghosts all the time. There are only so many active things that ghosts can do (stare, observe, hover, haunt.) But I like to force them to also interrogate, poke fun, violently remember, maybe a little puking here and there, touching but not touching, the stealing of hats, entertain romantic crushes, experience sandwich and ice cream envy, and be beautifully haunty, generally. Because I just like to think that this is what they do.
