This one was partly inspired by a Peanuts strip. Charlie Brown is at Lucy's Psychiatric Help stand and Lucy asks him whether he prefers sunrises or sunsets. A similar conversation ensues.
These "Ice-cream Principles" aren't true (Not that I know of), and I basically just based them off the cliché that distinguishes "chocolates" and "vanillas." But I think they have some true ringings to them. I'll admit that I'm a "swirler" and like to consider myself a nice problem-solver.
