I have know this man for quite a while but only to say hello to then I began to wait for him and walk him to his car (after church service). He then invited me over to visit. He is 89, he is very frail but continues to go to a university to work regularly. His wife died a while ago. He has no children. He seems to keep in regular touch with many friends so not lonely. He is friendly, interesting. (I am 53, married children etc). After a visit this week he asked for a hug . I was surprised. Do think he is being friendly / normal or do you think he is looking for something else ? I don’t know whether to go again.
