I mean they gossip about you in their language, right in front of your face..hate that..
Hm, had that once over here. I was standing at a busstop and behind me there were two guys talking about me, making fun of me in Dutch. When the bus came, I just smiled at them and told them in Dutch: "be careful what you say in your own language. Somebody might understand what you're saying." They were embarrassed to bits and I had a good laugh about it in the bus :)
Edit: mfeva, they do that with me too. What I usually do if they do such a thing is: make comments about their b**bs and *ss or face (when they are female) or how stupid they look (when they are male) straight to their face in Dutch. Just tell them in Dutch that you think their b**bs are a bit small compared to their *ss and so on. Just talk to them like that in Dutch. It works :)
Edit2: but be careful to use Dutch words that mean the same, but can't be traced back to English. So instead using the word "titten" or "tieten", which can be traced back to "t*ts", use "memmen" as there is no way in cold hell they will be able to trace this back to "t*ts", even though it means the same :) For *ss you can pretty much use any Dutch word for the bodypart as nothing is easily traced back to English. But be careful too to make sure it can't be traced back to German either, some of those buggers can speak German, you know.
