BFF... already?

On the way home today, Venice tells me she has three BFFs. "Katherine, Grace, and the girl in pink and white."
I asked, "The girl in pink and white?"
"Yes," she replies.
"Hmm. And what about Shelby?" I ask.
"Oh yes. He's my BFF in the boy catagory." She says.
I'm still amazed that she even knows what a BFF is!
