I Can't Remember Anything by Arthur Miller
This is a lovely, gentle, poignant play which studies two old friends, an elderly man and a woman who live in nearby houses and often have their meals together.
The gentleman is a retired draftsman and the lady is a wealthy widow; both express their sorrow at the passing of better days and the lack of contact with family and loved ones. Their memories are failing and they are unable to see any meaningful life ahead.
