Here in our house our favorite phrase for affection is, "I love you to the moon and back." If you ask any of the girls how much I love them they will quickly tell you "Mama loves me to the moon and back." I often overhear them telling each other that same thing.
So tonight, after a very lengthy bedtime conversation about our upcoming trip to the wedding, when Ella said to me, "Mom, do you know how much I love you?", I said, "to the moon and back?" She said, "Nope, we learned at school that a circle has no end, so that's how much I love you.... and please tell Daddy that's how much I love him from now on too."
