Have you ever had one of those days where try as you might, what you're working on just fights you tooth and nail? So you put it down and walk away from it, yet like the very mature "grown-up" that you are, you wind up sticking your tongue out at it every time you walk by?
You can feeeeel it taunting you, "Come finish me! I'll cooperate this time; you'll see. Really. TRUST ME!"
Like Eve biting into the forbidden fruit, I pick it up again, knowing deep in my heart I shouldn't. The temptation is too great. As crazy as it sounds, I would swear the paper clay face I sculpted suspiciously changed from smiling at me to smirking.
OK, I may be exaggerating for dramatic effect, but you get the idea!
