Well I had a few friends in high school too. Heck even when they had the senior slide show I wasn't in it. Why? Because I was took vocational class (commercial art) at another school. So when they asked for senior pictures, I was never there. Then when we had the award ceremony and had the slid show showing, my parents were pissed. We wasted 3 hours sitting there, to NOT see me get anything or even acknowledged.
When people did notice me it was never good. Some popular kid trying to make me look bad or make fun of me. MAN I wish I could see them now.
So yea I guess I was an invisible outcast, one who's only purpose is to make some popular jerk look better to everyone else.
