I've never been so lucky as to have an office overlooking a golf course, but I used to have one looking down into the main rehearsal studio of Northern Ballet. As they got nearer to production of a show they wore their full costumes for rehearsal and it was a beautiful sight. I stood there for ours gazing!
However, one morning a girl came into the hall in her leotard and settled into a splits position, not fore and aft, but sideways with her back to the wall. I was in agony just seeing her. But then she started slowly bending her upper body forwards, keeping her back and neck utterly straight, until she touched the floor with her nose. Then she raised her back slowly until she was once again in contact with the wall. She did this a number of times. It was terrifying to witness and I had to leave the office!
