Do you have a mother?

Over the past few days, the girls have been getting to know and playing with the kids across the street. The mother of the family works with me. We used one of their 7th grade twins to babysit for us once for a few hours in a pinch. They have a younger son, age 8. The 8 year old boy has been coming over and asking to play with the girls. They've been all playing outside together - in their backyard, our backyard or throwing a ball out front. The 7th grade girl and sometimes her twin brother, have been playing with the kids too. Funny, they've not played together all summer, and now that it's getting cold, they have become friends.

My co-worker came in today and told me about the following conversation that A had with her daughter yesterday:

A: "Do you have a mother?"
friend: "yes, of course. Everyone has a mother."
A: "No, not everyone. Sometimes moms get lost."
