Cinderella, Cinderella

Yesterday evening, my phone rings. My brother was on the other end and our conversation went like this (Names have been removed to protect the innocent):

Brother: "Hey, I'm just calling to tell you that we might be calling you in a few minutes, but you need to act like Cinderella."
Me: "Um, okay, why do I have to act like Cinderella?"
Brother: "We told Daughter if she goes pottie on the big girl pottie that she could call Cinderella."
Me chuckle: "Okay..."
Brother: "Okay, we'll call you in a few minutes."

So I wait a few minutes and my phone rings again.

Me: "Hello."
Brother: "Hi Cinderella, Daughter needs to talk to you."
(Brother gets "daughter" on the phone)
Brother (in the background): ""Daughter", say hi to Cinderella>"
Me: "Hi Daughter, it's Cinderella." Daughter (with a little coaxing from her mom and dad): "Hi Cinderella, I went pottie in the big girl pottie and I get to wear Cinderella panties."
Me: "Daughter, I am so proud of you. You are such a big girl." Sister-In-Law (in the background): "Daughter can you tell her what other princess panties you have?"
Daughter: "I have Snow White and Aerial."
Me: "Did you know that Snow White and Aerial are my friends?"
Daughter (to her mom): "Cinderella has friends?"
Me: "Daughter, do you get to have a jellybean for being a big girl?"
Sister-In-Law (in the background): "See, even Cinderella knows you get to have a jellybean for being a big girl."
Daughter: "Yes, I get to have a pink jellybean."
Sister-In-Law: "Okay, tell Cinderella you have to go so you can get your jellybean."
Me: "Bye Daughter, Cinderella is proud of you>"
Daughter: "Bye Cinderella."
Brother: "Thanks, Cinderella."

Oh the innocence of a child. Can it get any sweeter?
