Let me just add this:
Now you start pissing again.
I am not pretending what I am.
I am neither showing off nor do I need to show off.
I wrote "please do not take this as an offense" (what you obviously forgot to quote), and I meant it. So, no, I wasn't "pissing", at least it was not my intention. But as my English lecturer said: "Whenever a German speaks English, it' sounding rude, even if he doesn't want it to."
