While I agree that romanians integrate easily into the local culture (especially when the local culture is italian, french, belgian or spanish) I don't fully agree that romanians distrust each other completely :D. There are 3 classes of romanian immigrants that don't mix with each other:
1.The engineers, medical workers (doctors & assistants) and programmers: These are the silent romanians, one barely notices. 2.Construction workers and other low paid workers: These are the generic romanians and 3. The romanian gipsy group composed of organized beggars, pimps, prostitutes and thiefs = the bad romanians. When I hear someone talking romanian outside of romania, I try to classify him, and if he belongs to 3, I stay as far away as posible.
