When people think that you're mad or sad because you're quiet and you have RWF (resting witch face)

*me just sitting at desk*

*person walks up to me* Hey, why the long face?

Me: What? What do you mean?

Person: You just look so sad.

Me: I'm just chillin'

Person: Are you mad?

Me: I said I was just chillin'

Person: You don't look it. And, wow, I didn't know you spoke!

Me:  -_-
