My face is like my personal snitch.
It betrays me by revealing what I'm feeling.
The crease in my forehead shows worry, in some cases, anger.
My quivering lip shows that I'm about to cry.
My rapidly blinking eyes are tell-tale signs that I'm holding back tears.  
The twitch of my nose shows me being *******.
My scrunched up mouth is me holding back my sharp tongue.
Oh, why face are you such a snitch?
