Rest/ travel day, no running
It used to be weird when in public someone is seen talking to him or herself. Instinct is to walk around, shun eye contact, and avoid them like a plague. That is not the case anymore. Sitting in the airport, I hear people’s one-way conversations all around (presuming it’s Bluetooth and there is someone on the other end of the line).
As a corollary, wearing headset in public was a symbol of being antisocial. The underlying message implied do not engage or don’t bother me. Now looking around particularly with the younger generation that wearing earbuds is as common as a standard accessory like a ring or watch. Not antisocial and definitely no big deal.
Stereotyping or a sign of the times perhaps?
Have you examples of other changing styles?
