A Long Day's Journey Into Stan

Plot:

Having broken up with Burton, Christine forgets that she has switched nights of care-taking of Richie with Richard since she was going to see a play with Burton. She wants to switch back to the original schedule, but Richard has already other plans for the next day. So Christine concedes and ends up spending the evening alone, since Matthew is with his new, clingy girlfriend Natalie (who is never seen again after this).
