That's a pretty majorly Japantastic way of thinking there.And "sumimasen" is a pretty handy one too!
means "Excuse me" or "I'm sorry"Isn't it laying it on a bit thick?That's the one!
But it's a little different... how do I put this...?Like asking for favours, and greetings...And you can use "yoroshiku" in other places too, can't you?Just by whacking a "sumimasen" on, you can get through about most anything!
