When etchings aren't enough...

As you spend time with people you might notice that some have special verbal and non-verbal routines. They might have sentences or word phrases or concepts or gestures that recur for any number of reasons, one of which might be to impress others. Watch someone you know well, who fits this description, meet someone new. You might catch them prancing their "lines and looks" out from the barn, one shiny new pony at a time. Sure it can be annoying, but if there's one thing I've learned it's that annoyance is just a low level reaction. Once you get past it, you see that these behaviors are nice actually. Something that comes with the species: The act of self creation. But, dear reader, when a Frenchman selling chocolates uses one of your own classic "lines" on you, out of the blue, what do you do?
