Then so will you, right?

If I smile people will think im okay
If I smile they won't ask me what's wrong
If I smile maybe I'll believe im okay
If I smile the troubles of the world are washed away
If I smile the darkness knows to keep it's distance
If I smile then world becomes a beautiful place
If I smile then you won't cry
If I smile you won't lay sleepless in worry for me each night
If I smile...It would mean I'd've remembered how to...
