You were a drawing. More specifically, an animation, made by Alex. He loved animating, but had no idea that you were alive and had free will. Not only that, but you could also move to any electronic thar was connected to wifi, and even go into apps on his phone and tv. But you only ever moved freely when he wasn’t there. And when he was, you just returned back to the original frame he had left you as. This time though, you wanted to be seen. So as Alex sat down, put his headphones in, and picked up his stylus, you move to his phone and start talking, scaring him so bad, he falls out of his chair.
