"Um...no." you say, as you take in a nice whiff of the man's months-unwashed ripe aroma and his straight-out-of-GQ hobo good looks.
Before he can mumble another word, you punch him in the nose and run straight out of the alley. He falls backward into a dumpster, his legs flailing in the air. On your way out of the alley, you smash straight into an old lady carting her weekly groceries down the sidewalk, spilling old lady and groceries everywhere. Appalled, you help her to her feet, then punch her in the nose too.
Unable to take much more of this elderly lunacy, you run along down the street, amazed at your crazy day so far.
