The 6 y.o.: Wanna see the book I checked out from the library? It has a doppelgänger of Fergus on the cover.

The 14 y.o.: A what of who?

The 6 y.o.: A doppelgänger. Of your dog. The cairn terrier?

The 10 y.o.: Ok – I’ll ask the obvious question: what’s a doppelgänger?

The 6 y.o.: It’s someone who looks exactly like you, but isn’t you.

The 10 y.o.: Like a clone, right?

The 6 y.o.: Did I say clone? No. I said doppelgänger. A clone IS you. A doppelgänger is someone else who looks like you. Don’t they teach you anything in 5th grade?
