Do you?

[JohnS]

Do you? 

Do you ever wonder why
The sun sets and the moon shines?
But you stay the same
Never changing 
Always so dark and sad.

Do you ever think about how
The moon can be just as bright
Even on the darkest night.

Does it ever cross your mind
That maybe you’re not alone 
In this thing called life.

Hi,

I agree the question mark should come at the end of each stanza.

S1L2, you may wish to consider making the moon "rise" to give a feeling of the continuity of these events.

S1L5 Do you need both dark and sad? Melancholy?

Good start, write on!
