They may have had a religious upbringing and, at the very least, tend to be conservative. Romanians are very well mannered guests. They will come well dressed, usually accompanied by their spouse and always with a gift for you. When they are your guest for the first time, don't leave them to fend for themselves but be an attentive host. It's easy to find something to talk about with Romanian people, although some subjects remain taboo.
Current events are very popular and sports are always worth brushing up on before any meeting.
Politics are an acceptable topic among older men and will be hotly debated by them. However, people in their twenties are less informed and not impressed by the current political establishment. Questions about family and especially children would be greatly appreciated. Romanians also love to talk about their country and will want to know what your impressions are of it. Even Romanian history is an acceptable topic.
