It's a fundamental question of modern existentialism: we know we shouldn't be ordering extra, but we do it anyway. Is it because we're secretly trying to prove to ourselves that we're still young and carefree? Or is it because, deep down, we know that a little extra cheese is the key to a fulfilling life? We're not sure. But one thing's for sure: we're not giving up our extra cheese anytime soon.
It's a slippery slope, but someone's gotta slide.
