not to be an ass, but most of this is total bullshit.
i have spent my days in japan, and i didn't find myself in any situation
that made any of my japanese friends, or any other japanese citizen react or
turn heads for the things you describe..

sure, the number thing is correct, and hospitals don't use these..
and some other things are correct to, but they dont kill you if you talk
about money or WW2, do you really think they care if you bring up a money issue you have with your granma?.. ( ¬.¬) .. anyway, I regulary used these numbers in any given situation, and nobody gave a damn f**k.

i assume you read a book written by japanese authors that describe the
japanese people.. or read an article about japan.. and thats nothing wrong with that.. i did to.. and when i landed in japan for the first time i realized the book was written by some psycho, fuc*ed up bitc*es.

Have you been to japan?? If not, i really hope you dont believe that bullsh*t.
If you are Japanese, i feel sorry for you..

god dammint!! Now look what you made be do! i have lost 5 minutes of my life and im never going to get them back.. SH*T!
