I will be there, so don't worry, be happy!
Without...
If the sun won't be there
Who will be happy?
If the moon won't be there
Who will be shining?
If the stars won't be there
Who will be sparkling?
If the sea won't be there
Who will make you calm?
If the mountains won't be there
Who will bring you satisfaction?
If the animals won't be there
Who will bring you joy?
........
If you won't be there
What's the purpose of the rest?
