jennifer: dr. brown i brought this note back from the future and - now it's erased.
dr. brown: of course it's erased.
jennifer: but what does it mean?
dr. brown: it means your future hasn't been written yet. no one's has. your future is whatever you make it. so make a good one, both of you.
marty: we will, doc.
