This is not the kid's real name

Me: Rory, I have to tell you something important.
Rory: What?
Me: We decided what the baby's name is.
Rory: What?
Me: John
Rory: uuunnnnnhhh is that a girl's name?
Me: No. It's a boy's name.
Rory: Okay.
Me: And you can call him Johnny for short if you want.
Rory: NO!
Me: You don't have to. You can call him John.
Rory: Johnny is his last name!
Me: John Johnny?
Rory: Yes!
Me: Silly, he has the same last name as us! Walz. John Walz.
Rory: (has left the room and moved on with her day)

In short, the kid has a name. And we're not sharing it yet.
