There was a time not too long ago when people speaking aloud on the streets, alone, might elicit a glance, a stare or an avoidance of some kind. But now I hear a stream of one way conversations that does not alarm the passersby.
We all assume, correctly or otherwise, that the person is engaged in a conversation with someone else via some means of technology.
But the prevalent solitary chatter still catches my ears and eyes.
I suppose as long as we do not forget how to speak to each other face to face there is no need for concern.
