I think what he did was great.
You may be right David, about why the crowd cheered-but I like the fact that he ripped up the "approved" speech and said what he wanted to. It's his day in the sun, he worked hard to graduate, he should be allowed to give a speech without someone having to comb it over for "approval". Do they not trust the kids they teach to speak their mind without "approval"? And, what makes the person "approving" the speeches so righteous to decide what's ok and what's not?
Thanks for posting this link Steve
