"shadow fight"

i was invited by my boyfriend who was a dancer in a ballet company. i watched them perform/practice every night and got an invitation with a ticket in an envelope one for each night of the run of the production. i watched them practice and they moved so beautifully, i could watch for hours even though it was all the same each time and i would watch it over and over again. there was one particular scene that my boyfriend described to me that was ingenius. two male dancers would dance in a way that looked like they were fighting, but rather than actually make physical contact/attack each other physically, it was only their shadows that were supposed to be followed/ seen by the audience, for their shadows would fight one another and the two men would stand a little off from one another and appear like two independant dancers, but were actually engaged in a specific dance with each other. in any case, i asked the director/coordinator/coreographer how he intended to direct that scene, where the light was going to be placed for the best effect, discussing how the two dancers behind a screen with a light directed towards the audience so their shadows appeared on the screen would not be the best becuase the dancers' shadows would not be as sharply defined as it would be if the light was directed away from the audience so that the dancers and the shadows on the wall would be more visible to the audience [reading this now, I don't see the logic in my suggestion]. at one point in every night/practice/performance, the dancers did this little traditional kind of huddle with a handful of other dancers, those closest to them at the time, so that a number of huddles appeared on stage/behind stage, and they did it for warmth and to gather up their courage? or some other thing before practicing/performing. during this time, it was not uncommon for a couple, for a male dancer or two to steal away with their girlfriends behind curtains for a quickie. my boyfriend did that at one point. we were behind curtains, another couple was on the floor near us, she beneath him. my boyfriend had me against the back wall (legs around waist) of a prop with the curtain separating us from the prop and from the audience's view. meanwhile, there was a huddle nearby, within sight but no one would have stopped us other than the director and stage managers and such (because their cue was coming up and they had to go onstage or something). in the window above and near us as we were making love, in the cream brick wall, i could see it was raining hard. there was a warning for a storm that night. i don't recall ever leaving the building where the performance was being held, i was always near at hand for the dancers and the director.
