The energy from the sun caused his neighbors' mailboxes to fade over time, and since his mailbox was new, it was not faded yet.
Something was probably rubbing the tops of all of his neighbors' mailboxes but not his mailbox.
Sound energy from passing cars caused the paint on the top of the mailboxes to fall off, and since his mailbox was new, the paint has not fallen off yet.
