The nights are lonely, and so I go on walks to 7/11, where I enjoy Big Gulps and Slurpees, but these days mostly Big Gulps, of Diet Dr. Pepper, filled to the exactly correct proportion with ice. I walk home with my Big Gulp and sit, and not so long after finishing, I want to go back and have another, if for no other reason than to walk and pull the lever and fill yet another Big Gulp cup with drink.
