Barry, I am so sorry to hear this sad news. Your mom too will be in our prayers as it must be ever so hard for her to see her life partner struck with such a condition. She is fortunate in one respect and that is to have you and Fritz there with her to help lift spirits of both her and your dad.
You are correct to try to get your mind off the situation as best you can and we love seeing the pictures of Fritz, although I don't get around PT as much as I would like.
