Visiting Dad

I have been visiting Dad everyday. I don't have a minute to go into details. He's happy when I'm there. I take him on errands. He does complain of stomach pain occasionally. He seems to know a lot of people, but makes no effort to participate in any of the activities. He says he rather be lonely. He is forgetting whole days it appears. I put a guest book in his apartment, so please sign in when you come so he knows who comes to visit him each day.
