The face can not smile

How can it smile after smile has let it be isolated?
How can it smile after heart is devastated?
how can it smile when life never wanted?
How can smile pay it a visit after the hope dove away flew?
How can it smile when all pushed and none drew?
How can it smile when all left and none stayed?
Smile! pay it a visit once more, smile.
If it is not healed
If its tears you can not dry
Just again away fly
