Union Station. 6:30 p.m. i'm sitting on a bench minding my business when a homeless dude comes up and presents me with a flower.
dude: pretty flower for pretty girl
me (rolling eyes): huh. thank you
dude (shaking finger): do you know what that flower is called?
me: yes. it's a pansy.
dude (really shocked): gee, most girls don't know that. so could you spare me some change?
me: sorry i'm all out of change... would you like to give the flower to someone who does?
dude (shaking head): it's fine, just keep it. i can't believe you knew the name of the flower.
me: umm, sorry!
he goes off looking for other victims in clueless flora world.
