"Hi there. How′ s it going?"
"Oh, fine. Fine. How about this weather, huh?"
"Well, I guess we can always use the rain."
What is that? This story? Oh, just a little look at small talk. You know, those seemingly meaningless conversations you have dozens of times a day. Maybe you′re waiting for the elevator, or in a line at the bank. It all seems pretty trivial. Idle chatter about traffic doesn′t do much more than fill the air with empty words that are quickly forgotten. But you should know that small talk actually has a big place in our lives.
