What do the parents tell the kid when god doesn't write back?

I'll let Jack Handy handle this:

“If a kid asks where rain comes from, I think a cute thing to tell him is "God is crying." And if he asks why God is crying, another cute thing to tell him is "Probably because of something you did."”

"IS THIS FUNNY TO YOU, OR DID YOU JUST MISSPELL WAFFLE?!"

I don't think that it is expected that there will be reply to the letter, anymore than one expects an audible reply from God when you pray. The letter are just that...prayers written on paper.

Haha wouldn't writing the repies themselves be sacrilegious?

I was born with a deadly disease, and I agree with the notion that God writes back on my heart. He answers through the support of family and friends, by filling me with love during praise and prayer, by giving me moments of laughter, and by opening up my understanding that my illness is a blessing.

At a young age I learned to treasure laughter, to be thankful for a meal, to be grateful for the hours or days spent away from the hospital. While people my age took each day without pain or tears for granted, I learned to treasure them.

I am a more patient, empathetic, sympathetic and enduring individual because I was and I am sick. You can ask another to love you but them just saying it really isn't much of an answer is it?

When people love you they show it over time. They share their hopes, dreams, disappointments, challenges, and laughter with you. You know they love you when you become the center of their attention. Well a prayer to God is the same way. People usually learn His love for them over time; like a true friendship.

My parents told me that some answers are easy to give in a few minutes, while others can take much more time to receive. No matter how much we fuss; people will give us their answers the way they communicate; not the way we do.

Love is a process; not a demand. A relationship with God is a process; not a demand. That is how their letter is answered.
