All sorts of things. There are plenty of things to talk about. And it is nice to
talk to them about their life.
With my coworkers, the ones who are friends we settle into a kind
of province of subjects. I have talked with one a good bit about real estate, and
with another our conversations usually revolve around sports (though watching
sports isn't a very high activity in my life).
Now with piano and classical music, aside from my family, I talk with just a
very few.
Are you looking for ways to start up conversations, perhaps?
