I should add that I go out of my way not to feel isolated. E.g. I have invited for lunch... my cat Tommy's former owner, who is a very nice man. I will enjoy cooking for him and we will have a nice time talking with food and wine. Next I will invite all the volunteers from the cat rescue agency that I know - 4 women. A lot of cooking. But I like it this way, and I like being with people. Reaching out to cat rescuers is not your conventional form of being sociable, but hey, whatever works, right?
