Best Friend

Me:  *After we had been talking about her various friends for a few minutes.*  What about Charlotte?  Is Charlotte your friend?
Molly:  Yes.
Me:  She's your sister and your friend?
Molly:  Yes.
Me:  That's good.  You know Aunt Erica?  Well, she's my sister and my friend.
Molly:  Oh, my Erica.  My Erica is my best friend.
