Liam whistled as he hammered a new shelf into the living room wall, the air filled with the scent of sawdust. He was in the process of building a bookshelf for his daughter, a project he'd been planning for months. The hammering echoed through the shared wall, a sound that clearly reached Mrs. Periwinkle's apartment next door. A sharp rap on the door confirmed this. "Liam!" Mrs. Periwinkle’s voice was as sharp as the saw he was using. "That racket! It’s unbearable!" Liam froze, his hand still holding the hammer. He grinned and put the hammer down. "Oh, Mrs. Periwinkle, I’m so sorry! Just finishing up this little project here for my little girl; would you like a look?"
