I woke up to an ache in my chest, the smell of chocolate, and the sound of the ghost making a racket in the kitchen. Now, I'm not the sort to dwell on doom and sorrow. Life is too short for that. But I should at least try to describe the ache briefly: It is not the kind that comes from eating tacos too late at night. It's the kind that comes from being left behind. I think my heart is smart enough to know there's a place I should be filling with new memories, new jokes, and wondrous adventures with the one person I loved most of all. But that person is gone now. And so, my heart has a giant hole. I call it The Big Empty.
