Daughter or Dog?

We finally had some beautiful weather yesterday so we decided to have a family play day. We took advantage of the weather and played a game of croquet. It was fun. At one point during the game, Mark was trying to explain something to Leilani and raised his voice a little to speak over the wind. To which, Mia's response to me was, "Dad's talking to Leilani like she's the dog". Mark rarely raises his voice and when he does it is mostly to discipline Reshenka the dog so I guess I can see where Mia is coming from...she's a little confused, is Leilani a daughter or a dog?!? Okay, I don't get it...but it made me laugh!
