Article question. There are no articles in Russian, so it is a nightmare for me to understand where they should be used and where not. Yesterday I read that when we are talking about the things, which is obvious for both communicating parties, article “the” can be omitted. The example they provided was the following: you arrived to an airport and speak with another person there. The article is unnecessary in this case. Could you please confirm or deny it? Thank you very much to all! PS. By the way, is it polite or at least ok, if you read “thanks a lot in advance” in business (semi-formal) emails?
