Humor

Mary's sense of humor never ceases to amaze me. She makes plays on words and laughs at lots of things. How is that possible when a sense of humor is supposed to be a sign of intelligence and she is so obviously losing her mental capacities? Well, I guess it's not a sign of a certain level of intelligence.

She seems to be more and more tired and shaky. I try to remember to exercise with her but it's not easy btwn her sleeping and my doing stuff (and I never thought there'd be so much stuff to do).
