My dog and I have continual discussions about the state of the world. She requires me to talk for her which I am glad to do. I usually wave to a neighbor or two when I walk out to get the mail and sometimes we meet in the street and have a how ya doin' chat. If I have not seen my next door neighbor for a day or two I will call her and talk for a bit. She knows all the gossip. My niece and I text occasionally. So, I would guess every 3-4 days I have some kind of human interaction. That's enough for me.
