Rehearsal

There's a scene in the play I'm in where I'm being choked, and my fellow cop comes to my rescue. Anyway, I "fell" to my knees tonight during the "choking", worrying the actor doing the "choking" but pleasing the director who liked the look of it. 

I got confident at falls long ago, taking judo classes. 

I didn't master the martial art

But did okay at the falling part.
