Comparisons between Real Life and Online Friends

what do you exactly mean by "online friends"? are they the people whom you just chat with and not see personally? well, for me i try to be casual with the people i "meet" online (like in forums or in game rooms), and there's a limit to the info i give him/ her. i do not disclose personal details, and issues like i would with my real friends. it's always safe that way
