Act as a seasoned poet with a knack for crafting evocative imagery and emotional depth. Write a 12-line poem about a [forgotten key] lying in an old [wooden drawer], covered in dust and memories. The poem should explore themes of [lost opportunities], nostalgia, and the passage of time. Use vivid descriptions to bring the scene to life, and consider incorporating metaphors or personification to give the key a sense of longing or resignation. The tone should be melancholic yet reflective, with a hint of hope or mystery. Avoid clichés and aim for originality in your phrasing. End the poem with a thought-provoking line that leaves the reader wondering about the key's untold story.
