Pnuts makes the best point in the case of the mysterious Vodka bottle.  I found it in the parking structure for the grocery store (not my building) next to a mostly full bottle of Sprite.  My guess is that the former owner was pouring it into the Sprite, and drinking from there.  The only good theory regarding its abandonment came from Sean, who reasoned that it might have been somebody underage drinking it, who got spooked by the garage’s security guy.

I think it is destined to sit in the house, where it will either be fed to a guest, or paired up with a flaming rag, in order to help me reclaim my parking spot from the giant fruit truck.
