I think you are in good company, Babs. There are many people who go to the shop or catch a bus simply to speak to someone even at the most basic level.
I sometimes talk to myself just to make sure my speaking equipment is still working! I know people who have dogs or cats so they have an excuse to talk. Shouting back at the radio or TV works, too.
I go for walks and find people are ready for a brief chat. It can be two or three days, though, sometimes, between actually inter-acting with another human.
I think that is what prompted the setting up of the Silver Line. Maybe you could volunteer for them if you miss having a chat?
