Someone told me it was like the equivalent of switching characters in a game. He said he’d never seen anyone do that before. 

For example...this morning, I’m driving over to a coffee shop. It looked like I had a bad hangover and was sad asf. 

As soon as my foot gets inside the door, it’s nodding, greeting people left and right; smiling, shaking hands, laughing with the barista. 

Two hours later, I step outside. Whoa. Suddenly I have a hangover and look like I’m about to cry. 

What the hell? It’s so weird.
