What cultural faux pas should I try to avoid making in Bucharest?

"In Bucharest, it is polite to stand when someone enters a room and to look them in the eye when making introductions. Additionally, it is important to wait for a Romanian to introduce you to someone else, as it is considered improper to introduce yourself. It is also important to dress conservatively and be aware of public displays of affection. Refrain from talking negatively about Romania and the local customs and try to be respectful of religious sensibilities. Finally, asking an excessive amount of questions in formal situations is seen as intrusive, so it is best to keep conversations light and appropriate," mentioned another expat when asked about moving to Bucharest, Romania.
