thats what I would think because people used to steal my Sprites as well, it became a mission to me.

Some days I would carry one Sprite and drink it casually, other days I would drink half the bottle then pee in it and leave it unattended where I usually did.

And it got stolen as always. Some idiots drank my piss for about a year straight.

Also:

One of my roommates in college kept stealing my juice to pregame with his friends and then deny drinking it when I confronted him. I couldn't catch him because I was busy pledging a fraternity that semester.

Eventually I made a comment about liking watered down cranberry juice. The rest of the year, I would put toilet water into the cranberry juice and leave it in the fridge for anyone to help themselves.
