Oh wow... holy walls of text, Batman!
Well, first off, most of what she said doesn't make a lick of sense, especially the part in which people in the online world are "Dangerous, losers, creeps, & not real" as frankly, most anyone isn't like that.
Just about the only thing that I can say without going into further detail, is that I can find only one tiny little grain of truth in the statement, "If you don't go to parties, there's something wrong with you." The thing is, a lot of people think that if someone isn't being social, that there's something wrong with that person. Still, it could just be that the said person is a silent one that dislikes talking to anyone.
But in general, everyone's different in one way or another, & that there's no such thing as a "Stereotypical" teenager.
