A middle-aged couple wake up one morning naked in bed. The woman gently removes his hand from her breast, dons a handy silk robe and is off to the kitchen to make coffee. The man soon follows. But they seem unsure with each other; they don’t know each other’s names for starters. Heck, they don’t know their own names. Thus begins Lee Blessing’s A Body of Water, currently receiving a stellar production of its World Premiere new ending at Actors Co-Op in Hollywood.
