" I’ve given up on Lulu before. In Utrecht. In Mexico. But that felt like surrendering. Like it was me I was really giving up on. This feels different, somehow. Like maybe Lulu brought me to this place, and for the first time in a long time, I’m on the cusp of something real. Maybe this is the point of it all. Maybe this is where the road is meant to end. I think of the postcards I left in her suitcase. I’d written sorry on one of them. Only now do I understand what I really should’ve written was thank you.
“Thank you,” I say quietly to the empty house. I know she’ll never hear it, but somehow that seems besides the point. "
