I see my girl friend took the opportunity to post something under my name while I was away. Sorry for that.

IMHO your remark was funny, and my girlfriend's remark is rude (and from a Dutch point of view also funny). Although she did not mean it like that (English is just a bit too complicated for us to distinguish subtle and rude remarks).

So I hope no offence done, certainly not meant. My excuses again for having somebody else using my account. It will not happen again.
