 Tuesday, September 7, Assembly
 
 Okay, well, THAT was lame. Only one person was nominated for student council president:
 
 Me.
 
 I am apparently running unopposed.
 
 Principal Gupta is way disappointed in us. You can tell.
 
 I guess I am, too. I mean, I knew our school was apathetic, and all. Look how everyone rushed out and bought Diddy’s new album when they KNOW he is withholding information about Biggie Smalls’s murder from the Los Angeles police.
 
 But this is ridiculous.
 
 Lilly practically cried. I guess it’s not really a victory if there’s no one to beat. I tried to tell her it was because we did such a great job last year, people figured there was no point in running against us, because we would just win anyway.
 
 But then Lilly pointed out that everyone was just text messaging one another about what they’re doing after school during the entire Assembly, not even paying attention, so it was likely they didn’t even know WHAT was going on. They probably thought it was just another convocation on daring to keep off drugs.
