An old girlfriend is a gun in your belly. It's no longer loaded, so when you see her, all you feel is the hollow mechanical click in your gut, and possibly the ghost of an echo, sense memory from when it used to carry live rounds. Occasionally, though, there's a bullet you missed, lying dormant in its overlooked chamber, and when that trigger gets pulled, the unexpected gunshot is deafening even as the forgotten bullet rips its way through the tissue and muscle of your midsection and out into the light of day. Seeing Carly is like that. Even though we haven't spoken in almost ten years, it's an explosion, and in that one instant every memory, every feeling, comes flooding back as fresh as if it were yesterday.
