Sense of an Ending by Julian Barnes

Tony looks back at the life he has lived beginning with his school days in England.  He searches for old friends, learns of a tragedy he may have inadvertently contributed to, and tries to make sense of loves lost.  Mostly it is about memories.  Are the real events more true than the ones we filter through our own history?  Which of the two has greater value as a memory?  A short odd book that inspired a lot of book group discussion.
