>Interestingly, there are a bunch of other polite pronouns that have fallen out of use in most of the country, and have now taken on a sarcastic/mocking connotation (dânsul/dânsa/dânșii/dânsele for third person, and dumneata for second person).

Funny! I only know Romanian from my grandparents, and I haven't lived in Romania, so I thought these were fairly normal still :)
