El Dorado High School Principal Interrupts Valedictorian Speech

I was surfing the web earlier, and I ran across this clip on the KVIA Facebook page.  There is no story attached to it, but it gets a little uncomfortable because of ...

a confrontation between the Valedictorian of the Class of 2011 for El Dorado High School, Stephanie Paredes, and the principal, whose name is not revealed in the clip.  The principal stops Stephanie within a few words of her speech and puts her hand on the paper she is reading from.  Then it gets really awkward!

If you know anything about this incident that happened during El Dorado's graduation ceremony this Saturday, let me know!  I'm dying to find out what this girl was going to say that bugged the principal so much.  I mean, this same lady was singing her praises only moments before! 

Spill the beans and tell me what was going on!
