Does heaven have a phone number?

This is in the point of veiw of my little cousin

My Gramma went to heaven,
but i need her here today
I'm having problems, and you see,
I need her right away
Operator, can I find heaven
in the big yellow book?
Its very frustrating,
I dont know where to look.
I think mommy need her too,
sometimes i hear her cry.
Gramma left before her time
I need to ask why
Maybe if I call her
she'll come back to see me
Maybe she can't come back
but why did she leave me?
She's been gone a long, long time
and she needs to come home now!
I really need to reach her,
but I simply don't know how.
Help me find the number please,
is it listed under "Heaven"?
I can't read these big words,
I am only seven.
I'm sorry operator,
I didn't mean to make you cry,
I just need to call my gramma
I just wanna try
If I call my church,
maybe they will know.
Gramma said when we need help
that's where we should go
I found the number to my church
it was tacked up on the wall.
Thank you operator,
I'll give them a call.
