Embarassing Character Flaws
Everyone had a weakness that was the way of the world. Nothing in life had to be fair was yet another unwritten law of the world. But really, this just took the phrase 'cruel and unusual punishment' as clichéd as it was, to a whole new twisted level.
Voldemort glared at his nemesis in pure hatred, he could feel the air turn cold around him (a talent that often sent the most hardened persons rigid with fear) but this, this…thing continued to be unaffected. Just how had it gotten in? The place was supposed to be impenetrable! Nothing got in nor out without his express permission. A sudden movement in the thing's mouth attracted Voldemorts attention. It, much to Voldemorts dismay, was going to speak.
"I'm dreaming of a white Christmas, just like the ones I used to know", it sang.
Voldemorts glare increased tenfold, at the sound of the muggle contraption belting out Christmas carols. But inside he felt the knots loosen and the tension is his shoulders subsided just a little. Damn who ever gave him a weakness for muggle made singing elves. This was the reason for several attacks on muggle shopping malls, the more that were destroyed the less chance there was of someone finding out this particular embarrassing character flaw. Grabbing his wand he began to burn holes into the elf's eyes all the while secretly enjoying the melodies it continued to sing, oblivious of its destruction. "Really, they need to be destroyed", he thought as he began humming Rock around the Christmas tree.
