At the small-town workshop, tiny gears kept vanishing from the workbench, puzzling Sam, an amateur engineer. Teaming up with his coworker Lisa, they noticed faint finger smudges leading to the next-door garden. They soon found a curious child building a school project and borrowing gears without asking. After a friendly chat, the child returned the parts with a handmade thank-you card, sparking new friendships in the community.
