You turn around and look behind you. A few meters from you stand a man. He leans up the low wall. Beside him lays a bouquet of of roses. He is wearing a thin shirt and thight new jeans. He smiles at you and put his hand into his pocket. He takes out a little black box and hand it to you. You take take it slowly. You open the box and find the ring you dropped. As you look up the man is gone. The roses lay on the wall as the only proof he was ever there.
