hero99 - that girl who said "Hi, how are you doing" sarcastically is a fake person. If I throw a stone, i'd probably hit someone like her or her. She's making socializing out to be a competition of who says more or who puts up a better pretense. If you didn't feel comfortable, i imagine somewhere you sensed the people around you, the girls, were playing the game of who is more social which made you quiet. If you have something to say or contribute you'd say it. Few people in social settings talk completely honestly, so if you do reveal your authentic self, you'd be putting your heart out there. Don't do it! Instead, make it a point to know interesting, but light facts or topics - the news, entertainment, beer & sex statisics, jokes etc. I didn't like you sympathizing with the dumb girl (i.e. "I knew what she meant by that...I didn't say a whole lot to her and just left in my car"). Did she say a whole lot to you? What she did was wrong, and cowardly. Don't let dumb people's words make inroads into your consciousness.
