The late night seemed to be too quiet and only the sound of the wind and your walking could be heard. At one point you stopped to pull out your phone and look at the time. But suddenly someone puts a hand on your shoulder and you hear a familiar voice.

“Oh, why are you walking at this hour? Aren't you afraid some maniac will steal you or kill you?”

You recognized the voice immediately because it was your friend Joe. He seemed as cheerful as ever, but his voice was a little different. It was deeper and more mysterious.
