[I've been
The Housekeeper and the Professor

Really enjoyed this short poignant story about a lower class woman who takes care of an older man with a serious memory problem--he can only remember the last 80 minutes of his life, and things that happened before 1975. The older man is also, was also, a mathematics professor and his mind still engages with math problems even as he has to keep slips of paper attached to himself to remember who his housekeeper is. Lots of levels to this book including baseball and, of course, math.
