Relations

Reagan: "Dad, will you be my sister?"
Dad: "Yeah, sure.  I'll be your sister."
Reagan: "You're my sister, and Reagan's your sister."
Dad: "Now I have two sisters... Aunt Diane and Reagan.  But you're still my daughter."
Reagan: "I don't want to be a daughter.  I don't like daughters.  I want to be a son."
Dad: "You'll always be my daughter."
Reagan: "I don't like daughters.  I want to be your son and your sister."
Dad: "Oh, okay."
