My mom used say this to us all the time when we were little. She would tuck us into bed and we would say, "Mom, I love you to the moon" and she would respond "Well, I love you to the moon and back!" I've been really missing her lately.
I am Not Your Friend. I am your parent. My mom was saying this to me long before it became popular. I was so envious of my friends' parents even though even back then I thought they were a little slow. Sixty years later I'm glad my mom was ON IT !
