And don't you forget it!

So I was on my way to lunch with my daughter, who feels the need to know everything. She was busy asking me where are we going? who are we meeting? and what not. So I got to work answering all of her questions. I said "We are going to lunch to meet your Nana and Aunt Daphne." Emily responds "Dapne (as she pronounces it) is going to be there?" I say "Yes, AUNT Daphne is going to be there" Stressing the aunt to encourage her to use it, and then in one of my brilliant mommy moments the idea comes to me, Maybe if I explain to her why she is called Aunt Daphne she will remember to use it. So the rest of the conversation goes like this: "Mommy and Daphne are sisters, that makes Daphne your aunt." She responds, "No, Emily's a sister." I say, "Yes, that's right you are, and just like you are Corbin's sister, Mommy is Aunt Daphne sister." Then my child who is obviously frustrated by my stupidity responds in her I've told you once, don't make me tell you again voice, (which she has mastered by the way) "No, You're not a sister, You're a WIFE!" Wow, and don't you forget it.
