Oops, I'm really sorry.
I didn't mean to offend at all. It's just my bad habit since I'm into linguistics and translations. I really, really appreciate your help, and if I did anything that offended you, can I take my words back? I will make sure I will not let anything like this happen again.
Edit : To tell the truth, I always have a fear when I post my questions on this forum. I know very little about the way Japanese people think, so I fear that I may end up offending them someday. This fear is even more serious than when I ask my teachers questions. I only ask here when I can't find the answer I need elsewhere. I know it's a privilege to be answered by a native speaker, so I always try to preview and edit my post carefully before and after I posted, unlike when I post on other forums. However, there is no guarantee that I don't make any fault. Today I really went overboard and did it, so I sincerely apologize. I only have one goal, and that is to understand the language I learn as much as possible.
