I am sorry the inventory thing has been dealing with several months instead of several days like over ten years ago in your memory.
I am sorry, during the past ten years, it seemed nobody could deal with the inventory things well, for some reason that I don't know.
I am sorry we are not as good as the people who worked here ten years ago.
I am sorry you can not hire employees as many as ten years ago.
I am sorry I can not appreciate you as people appreciated you ten years ago since my salary is the same as ten years ago and you think it's reasonable.
I am sorry I declined the job at the University of Vienna. You thought what I concerned was foolish. What you did not speak out was that my decision also disrupted your future plan.
I am sorry everything was difficult since your latest wife passes away, or even earlier when she was sick.
I am sorry I can not accept what you complained about the other three women. I guessed they were also called "your wives", at least they were mothers of your three children. It's none of my business.
I am sorry I choose to leave. I still desire to lift but not chase the stable life as many EU citizens.
I am sorry I have to leave you far away. I should change a new system, like Israelites stepped out Egypt a long time ago, stepped out of the comfort zone. What you told me before, about how you can be my resource when I work at the University of Vienna, revealed the inside message was: you still plan your empire and I am just one of your chessmen.
I am sorry I am not stupid. I can not find out my value from your lab. Nevertheless, it doesn't mean I can't find out from outside.
I am sorry my language ability is lame, yet, this can't represent my brain is lame.
I am sorry I read the news often and I quite understood you were bluffing.
I am sorry I am not stupid enough to accept all your statements.
I am sorry I reject to be a buffer between you and the colleague. It may be important to you because there was a conflict between you two. But it's nothing important to me but only waste my time and energy. It was just disparaging about myself.
All these "I am sorry" just want to tell you that: I feel sorry for you! Yes, I mean it!
