Ponder and wonder....

Sometimes i cant help but keep pondering and wondering about on9 virtual life and real life... I mean when u on9 and talking it is like it isn't u anymore, when someone goes on9 i believe that their personality will change.lets take for example : a guy labelled X in real life is a completely quiet,innocent and extremely shy guy ,However in the virtual realm , he is like the exact opposite of what he is in real life- talking non-stop and on9 24/7 and etc etc...I guess this is what ppl call alter-egos or the inner self of somebody right? Well , we can deduce here that sometimes , ppl talking to u on9 might not be the same when they talk to u in real life. Here is another example to illustrate this effect:

Let's back to X , X well as stated in previous example likes to talk on9 with a lot of ppl, however in real life , he is just another quiet ,innocent and extremely shy guy.Let's say one day , his best on9 fren(to make matter worse, lets assume it is she) whom he never meet be4 in real life Meet him COINCIDENTLY and say "hi , X how r u ? ".Being an extremely shy guy , what would X do facing this situation?
