Conversation between Bella and Lucas while they were getting ready for bed...
Lucas: You don't have a wiener, Bella.
Bella: I know.
Lucas: You have a vagina.
Bella: No I don't. Stop saying that.
Lucas: Yes you do.
Bella (not understanding Lucas and getting frustrated): No. I. don't!
Lucas (in his sweet, reassuring voice): Yes you do, Bella. We all have privates.
Bella: I. don't. have. privates! (not understanding what privates actually means)
Lucas: Yes, everyone has either a wiener or a vagina, a bum and armpits.
