Dear Cody James,
It is me, Susanah. Yes, I will be your girlfriend, but we have to keep it a secret from my daddy for a little while OK? I really love you a lot and I will even share my toys with you. We can share apple treats and I will make my mommy break them in half for us. If you do that right sometimes she forgets how many you've had and gives you extras.
I love you.
Susanah
