After Graham stopped returning my texts, I started leaving little parts of myself all over the Internet. In his early twenties, especially, Graham left doorways to himself everywhere—not just the normal abandoned social portals of MySpace and Friendster, but also a blog with a cursor shaped like a hot pink mouth. When I clicked on an entry, the disembodied lips smacked. Sickened, I kept clicking as the computerized sucking noise pulled me into page after page of journal entries, photos, digital check-ins at bars where he’d time-stamped his arrival.
