The audio begins with the distinct sound of footsteps on a gravel path, creating a sense of anticipation. There's a slight rustle, like the swish of clothing as the person moves. Suddenly, the metallic creak of a mailbox door being opened fills the air, the sound echoing lightly around the quiet neighborhood. The mailbox is old-school, made of metal, and it's clear that it's been installed outside a house, a common household item. The sharp clink of metal on metal is heard as the latch is released and the door swings open. You can hear the rustle of letters inside. Then, the mailbox door is shut with a satisfying clunk. The sound effects are incredibly realistic, giving the listener the feeling of being right there in the moment. The audio ends with the retreating sound of footsteps, leaving behind a sense of completion.
