Excerpt from this article:
When you talk to someone on FaceTime, there is a little square of your face in the corner that gives you a self-awareness you would not get on a date. It’s as if you’re holding up a tiny mirror in front of yourself during the entire conversation.
He tells you a story, you respond and then think: “Don’t react too hard. Your eyebrow lines are getting deeper. Maybe it’s time for Botox, but what if Botox makes your eyelids go limp for a month? Also lift the phone higher; you have a double chin. Oh hey, you should look as if you’re paying more attention.”
