Bed Time Story or Bed Time Prayer?

Today I laid down with Isabelle and Grace to get them down for a nap. We laid down and Isabelle said, "Mommy, can we pray before we sleep?" I said, "Sure, Baby. Why don't you pray." So Isabelle says, (as usual) "Father, thank you for Mommy, Daddy, Grace, and good food. The End." I then asked her (while surpressing a giggle)"Don't you mean 'Amen'?" There was a pregnant pause as the pieces fell into place and she said, "AMEN!"
