Orphans?

The girls played outside this evening until I made them come in. It was dark. They had been running and playing and obviously involved in some elaborate make-believe. When they came in, Mia said "I have new Mommy and Daddy." I was a little confused.. and asked what was wrong with her old Mommy and Daddy - Ali explained, "We were playing that we were orphans. You and Daddy took us to Audrey's (a friend) house on your way to New York and we were orphans there." Mia says, "Drop me off please. I get my coat."
