I was just trying to be nice.
To me, it isn't a question of being nice or being rude. As a member of the United States military I understand that there are men who came before me who have given their lives to ensure that I speak English rather than German or a number of other languages. It's the least I can do to not piss on their graves by sounding like I speak it as a second language. Other people like to say they are veterans (frequently) and yet their command of the language is an eyesore to look upon. Anything worth doing is worth doing well, I just wish that other people had the same mentality that I do.
