nexusc, no stories in particular. just having fun writing nonsense.
many foreign guys have really good japanese (far better than mine), but they're either ultra-polite (which comes across as aloof and impersonal), or they sound like their (japanese) girlfriend. another danger is sounding like an anime character*, or a samurai. i guess it's good to aim for a wide repertoire.
my secret with other languages in college was to imitate a close friend, my dorm roommate, or a movie actor. all safe bets. in japan, i felt like i was always fine-tuning and ditching overly polite speech or expressions i learned from female friends that made me sound, shall we say, flamboyant.
having said that, i think being able to talk like
ebichu** is my goal now.
*makiko has a good story about someone who fit the anime character category, complete with sound effects.
