I wonder, how to emphasize, that communication happens, say, in real life, when you are in the same place and see each other, not over the Internet. Also, are there other ways to stress that you're communicating over the Internet, except for "I'm chatting over the Internet"? Or how to put it the other way around? In fact, you're welcome to suggest variants for both English and Russian languages, with English being the preferred one though. Thank you!
