Should - Could - Would

I should feel blue
But I couldn't
Because I wouldn't

I should be angry
But I wouldn't
Because I couldn't

I should hate
But I couldn't
Because I wouldn't

I should shed my tears
But I wouldn't
Because I couldn't

I shouldn't stay away
But I could
Because I would

I shouldn't stay quiet
But I could
Because I would

I shouldn't forget it all
But I could
Because I would

I shouldn't forgive
But I would
Because I could

I shouldn't move on
But I would
Because I could

I shouldn't because I couldn't
I couldn't because I wouldn't.
But because I should that's why I would;
And I would that's why I could.
