The olive theory is a simple one: it determines the (potential) success of a relationship based on whether one person in the relationship loves olives while the other hates them.
Naturally, upon hearing this theory, Tim wants to test it out. And who better to test it with than his rival? Just for shits and giggles, of course.
You're ready to sigh and roll your eyes at him when he walks up to you. Then he asks you something you never thought he'd ask: "What's your opinion on olives?"
