In truth, we are just 'acquaintances' since internet does bring ppl together but also that 'friendship' is kinda hollow without face-to-face interaction. We know only small part of things about ppl we meet in game and on forum, and 90% of personality, true personality that we are is hidden under freedom that we have when we speak over long distances knowing that we are 'safe' in our homes whatever we say or do in this virtual life. To know someone truly is a hard and long process of being together in real life, sharing good and bad and acting the way we are, not the way we want to 'look', if u know what I mean.
So, Deridor just stated something that we all know.
