I just looked at your user page and you are Dutch. I've stayed in Bussum three times - I have a friend who lives there. Very nice country - the people are a bit too straightforward in their language for English sensibilities. Makes sense of your "fucking dumb ass paranoid" statement. Try to refrain from swearing in the future - its an English swear word anyway and we reserve it for war and serous situations.  
 Basically if an Englishman uses the F word seriously it generally means they are really annoyed and are considering physical action beyond the law against you.
