This is a pointless one shot. At least it's short, so it's even less worthless than it might have been. Nobody gives a crap about a non-relationship.
I didn't like it either, because I always want to see cute, fluffy, happy endings...
...but damn, you could not be more bitter about something so minor. It's really well done and elegantly put together, just a simple little thing from the heart, from experience. Even though it hurts, it's a well-made snapshot of a much bigger, true-to-life story.
