The world felt crisp, clean, and utterly alive. This morning, everything was… amazing. Liam was sketching in his notebook, a tiny smile playing on his lips. He loved this sensation, the energy zipping through his veins.

A massive thud shook the ground. Liam ran outside, notebook forgotten. Across the street, the massive pine tree in the Miller’s yard had decided to take a nap, right across their pristine lawn.

He practically skipped over. “Wow! That’s quite a mess!” he exclaimed, utterly captivated by the sight. He was already pulling out his phone, ready to document the whole thing.
