Bee, the heroine of Bruce Norris’s new play, A Parallelogram, is in the midst of a bout of depression. She sits on her bed playing solitaire. Perhaps it’s because she and her boyfriend, Jay, have recently returned from a vacation on a tropical island, where she saw grinding poverty. Or perhaps because, on returning from their trip, she found that the pet parrot she had for 17 years had died from her own negligence (its empty cage sits in the bedroom). Perhaps it’s the hysterectomy that she recently had. Or could it possibly be because her future self, Bee 2, has materialized to reveal the future to her in all its futility?
