The air in the attic was heavy with the smell of dust and forgotten memories, but for Ethan, it felt invigorating. He felt a light feeling, ready for anything.

He stumbled upon a collection of old letters, tied together with a faded ribbon. He sank to the dusty floor, eager to delve into the past. He began to read, lost in the intimacy of the handwritten words.

He discovered a box of old toys, a wooden train set, a teddy bear with one missing eye. He picked up the bear, squeezing it gently.

He felt an almost giddy delight. His mind raced with ideas, with possibilities. He knew exactly how he was going to spend his weekend. He couldn’t wait.
