Oh, we can't prove she's a demon. But we have evidence. True story: when she was just a little baby, our mom was left alone in a high chair in the kitchen. All the adults, in the meantime, went into the livingroom. After a while, they heard our mom laughing. She was laughing louder than she'd ever laughed before. Finally her mom, our grandmother, went out to the kitchen to see what she was going on about. The entire kitchen was on fire.
She made the newspapers. The headlines went something like, Laughing Baby Alerts Parents to Fire. They made her sound like a hero. We have our doubts about this scenario. We've always suspected that she started the fire with her eyeballs, and then laughed at the thought of her mischief consuming the house.
Why nothing since? Well, either she lost the power of telekinesis, or she only practices it on birds in the backyard of our sister's house. Our sister and her girlfriend are always finding charbroiled birds in the backyard. Okay, so we made that part up. And our mom probably isn't a demon. But you should see the way she overcooks a pot roast. No stove could do that. She's doing it, and she's doing it with her eyes.
