Everyone has their own “street face” but have you ever practiced in a mirror? One time my girlfriend asked me why I was frowning at her when in my mind I had at the very worst a vague smile going on. I then realized maybe I have no idea what kind of faces I’m making, or that I’m never making the face I think I am unless it’s a big smile or frown. Those in between expressions are kind of hard. So I did actually go to a mirror and see what my various faces that I make looked like.
