Context:
Lying with Aidan just before bed. This is not the first time he’s brought up the subject.
Ronni: You want a sister?
Aidan: Yes.
Ronni: Why do you want a sister?
Aidan: Because I don’t have one.
Ronni: But why not a brother, or a puppy?
Aidan: Uh, I, um… uh…. I don’t need a brother! I’m already a boy!
FTR, there are no sisters or brothers in the oven. LOL.
