What? How? I don't know either.
Pretty much all you need to know about Charlie is that I sing the (first) refrain of "You Are My Sunshine" to him every night as I put him in his pajamas, and I mean every single word of it*.
Also, I wish this for him:
* You are my sunshine, my only sunshine
You make me happy when skies are gray
You'll never know, dear, how much I love you
Please don't take my sunshine away
