I find this kind of thing more pathetic and infuriating than really sad.  The thought of teenagers being that impressionable and losing themselves to much in the internet world, is pitiful.  Parents have to do a better job of making their children live in reality, and finding ways to make the responsible and resilient.  of course part of the problem in Russia is that the parents aren't good parents, as indicated by the drinking problem that leads to many of the youth suicides.  But I just don't relate to the idea of someone being so weak and vulnerable that they'd be convinced to commit suicide based on what someone wrote online.  I'm not a strong person.  At all.  But that thought remains completely foreign to me.
