"Îmi lipseşti" means I miss you, but it's rarely used. "Mi-e dor de tine" means I really miss you and it's more common.

You may surprised to see how many people in Europe speak Latin! I personally know 2 people who can speak perfect Latin. I've studied it for a year and I don't think it's useless. I know a good Latin site if you're interested...

I think the most beautiful is French, the hardest is Romanian and the most popular is English. I prefer my own language, of course, but I like all languages! :)

I'm not French, but I think it says "The work is the health, doing nothing means preserving it". Sorry If I'm wrong.

Well... Romanians sit around the table and eat traditional food (very unhealthy) and drink (quite a lot, to be honest). At midnight everyone hugs and wishes the others Happy New Year. Then, people go outside to watch the fire works (there are fire works all over the country at midnight). After that, they come back inside and party till morning. Some prefer spending the New Year's Eve at a concert. That's about it! :)

Hi! I think I can also help. :)

To answer your question briefly, I think the best way is to talk to the local people and discover their culture. Suppose you don't have the chance to do this, then you should do some research on the Internet (browse through the forums and stuff). At least, that's what I think... :)

I think you should read books in English to improve your vocabulary and also talk to others in English.
