Today I read an article written by an american auther,
the title is "How To Survive At a Japanese Company".
I'd like to quote some sentences from that article here;
"You will be asked many many times how old you are, if you have a significant other,where you're from - and in extreme examples - if you can use chopsticks.
They'll also compliment your Japanese ability even if you have none.
Any foreigner who has lived here for a time knows the questions and protocol of which I speak.
Refuse outright to answer these questions, or better yet, lie your ass off.
It will add greatly to the mystery surrounding you.and drive them freakin' crazy in a good way.
Japanese love comic book fantasy. Fulfill that for them.
