Confusion

I don't think Alta really gets all these familial relationships. Yesterday in the car we had this conversation.

Alta: "Where's Daddy?"
Me: "He's playing golf with Grandpa."
Alta: "Grandpa Palmer?"
Me: "No, Grandpa Brower."
Alta: (little pause, then using her hesitant quiet voice) "Grandpa Lorna?"
Me: (trying not to laugh) "No, Grandpa Mark."
Alta: (longer pause) "Is he the one that's Grandma Lorna's friend?"

Yes, she's definitely confused.
