It was my joke, at the top of this thread and the only one in this thread. Have you considered the possibility that you have no idea what is going on here (your lack of fluency in English is a likely factor) and that you have no business poking your nose into it, person who is attacking me with a hostile rhetorical question for no good reason? The fact is that I do put quite a bit of effort into being sure that I understand the context--a lot more effort than you and others here have.
