We just get home from a visit at Papa and Grandma Linda's and Abby asks Mike what's going to happen when she grows up.
Mike: Well maybe you'll get married and have a house of your own.
Abby: But how will I know how to get back here?
Mike: You'll always know how to get back home, Abby. Didn't we just come from Daddy's Daddy's house? And I knew how to get there.
Abby: Yeah, but you have a GPS.
