Mom.

Pete was telling the Nik this morning how he always gets comments from his friends that Nik looks just like him.  The shape of his head, his face, his smile.  Nik said,”Well, you’re my dad.”

So I asked Nik: “Who’s your mom?”
Nik: “You.”
Thinking I’d get a response based on the color of his hair, or his brown skin, I followed up with: “How do you know I’m your mom?”
Nik turned to look at me and said: “Because you take care of me.”

That pretty much sums it up.
