We want to empty your life of Clementine...

Howard: 

Now, the, uh... the first thing we need you to do, Mr. Barish, is to go home... and collect everything you own that has some association with Clementine. 

Anything. And we'll use these items to create a map of Clementine in your brain. Okay? So we'll need, uh, uh, photos, clothing, gifts, books she may have bought you, CDs you may have bought together, journal entries.

We want to empty your home...

We want to empty your life of Clementine.

And after the mapping is done, 
our technicians will do the erasing in your home tonight.

That way, when you awake in the morning, you'll fixind yourself in your own bed as if nothing had happened... 

a new life awaiting you.
