Boys have a wiener

Well the time has finally come where Lily has comprehended that there is difference in plumbing between boys and girls. She was sitting on the potty before bed a couple nights ago and this is a bit of how the conversation went:

Lily: "My pee pee is going down the hole in the potty. I put my weiner in the hole in the potty to go pee pee."

Me (laughing): "Lily, you don't have a weiner. You have a vagina. Boys have a wiener."

Lily: "Deven has a weiner and he puts it in the potty to go pee pee." (Deven is the only boy in her class at school, poor fella).

Me (laughing harder): "Who else has a wiener?"

Lily: "Daddy has a wiener. And Tyler has a wiener. Tyler's wiener is little."
