frown

Whats in a smile, Why do we smile?

I see you smiling, Is it for real?
Why are you smiling?Are you truly happy or just pretending?
You look at me and smile, I don't know what to think.
Do I trust you, because you smile at me.
Are you my friend or fo?
I don't know.
Is it ok to smile when your upset? Do you smile to hide your true feelings?
How do I sound?
I'm gonna turn my frown upside down!
