For happy:

She smiles and smiles
It's apparently her style
So even when the smile is fake
She keeps that smile for all of friends' sake
Smiles and looks tho' she's okay
Smiles and smiles till the end of the day

Back on her own in quiet solitude
She took off all the being cute
On her bed under cracks and dents
Where she could get away from all torment
A place she knew she could no longer grin
A place to finally express her feelings from within

Although tears are piling
It can't stop down-rolling
But she can't stop smiling
For Smiley girl knows
When she does smile
It makes one's day and that's worthwhile
