Stop in for a cup of coffee

Why would you talk to strangers anyways.

There is really nothing to say to someone you will likely never see again in your whole life.

"So how about them Minnesota Vikings "

Most families already know what's going on with each other and won't talk personal in public with stranger ears around
I might agree with you, but these same people were all talking up a storm with each other in the gate area in ear shot of everyone...but became silent on the plane.

I saw a group of 7 college students who were loudly talking, laughing and goofing around in the gate area but became completely silent once they got on the plane and pulled out their devices...even though they were all sitting together.

The psychology of the behavior was astonishing to witness.
