Confusion runs in the family

My grandma has had memory issues for a bit. It's gotten pretty bad lately. It makes me sad, but it is what it is.

I don't know really how I should be dealing with it. I'm trying to take queues (?) from Laura from how she deals with me when I have a headache. Really it probably isn't that different: forgetting words, quick to anger (for me at least), inability to remember things after a short time, forgetting what you are doing, seeing things, etc. Laura is always patient, calm, doesn't seem to mind being asked the same question every minute, etc. 

The more I think about it, the more I realize I have the best wife ever. I can't think of a more comforting thought.
