“I can put the phone in my pocket the second you start talking to me. It is not part of our conversation and there is no screen alerting me to a new message or enticing me with some video. Putting the phone in my pocket is a way to say, gOkay itfs just you and me talking now.h But wearing that computer on your face is a reminder that, well, you have a damn computer on your face.”
I agree.
