“Have a Good One!”

“Have a good one” is one of those empty phrases that people tack to the end of a conversation on their way out of the space they’ve just occupied.  It harkens back to the days of where we would have spoken something of the likes of “Good Day, Sir” and turned and walked out, except those phrases were useful.
There’s something about having that awkward moment of silence/s from the time we finish speaking to the time we exit the space we’ve just occupied.  Perhaps it’s the training, the habit we’ve seen on television where each conversation is so neatly crafted and packed.  At the end of each conversation there is a scene cut into a new situation.
