The man who, gleaned from Francis

People ask me "Who are you?" I am me or me am I Even after I reply "The man who." "The man who what?" "Who what? Just who." "I'd rather leave that up to you." "Oh," they say and walk away. People ask "Then who I am?" "How should I know?" I reply. "You are you" I suppose, "but could be him or them or those." "Or just me wearing different clothes." "Oh," they say and walk on by.
