poem - Lord's prayer

Poem found in a mailing from the Omaha Home for Boys:

You cannot pray the Lord's Prayer and even once say "I."
You cannot pray the Lord's Prayer and even once say "My."
Nor can you pray the Lord's Prayer and not pray for one another,
And when you ask for daily bread, you must include your brother.
For others are included ... in each and every plea,
From the beginning to the end of it, it does not once say "Me."
