Sometimes you just want a little bit of privacy whether it's at home or at work. Sure you can put your phone on silent and not respond to messages for a few hours, but then there's always some pesky person trying to start up conversations with you and get you to be all social.
I'm the kind of person who won't shut the hell up and about three minutes into my mindless blabbering I realize that I haven't let the other person talk. That's when a horrible realization dawns on me: I'm making the other person uncomfortable, but how do I know? So I could shut up and mind my business, which only lasts for so long.
What a guy like me could really use is some type of visual cue that's an unmistakable declaration that the person I'm in contact with doesn't want to talk to me.
It seems to have made Ruth a very happy camper.
