Even with a less than perfect memory, older people can often remember contradictory times, positions, activities and opinions. I noticed when teaching that a class I met at 10 was difficult to work with while the class at 2 was a real pleasure. A couple months later, I would find myself leaving a 10 o'clock meeting with a deep grin and then expecting a down session at 2 after a rough class the last time we met.
