Today I saw first real evidence that Hattie's hearing is deteriorating. She thought I went into the garage and was sitting in the laundry room facing the garage door. I was actually behind her, down the hall. I called her in a normal speaking voice and she didn't move, so I walked up, saying her name until I was directly behind her. She could hear me then but still thought I was in the garage. I had to touch her to get her attention.
Saw the same thing happen with Hooper and Tag, to some degree, in their last two years.
