She gets all generational, like I've mentioned before, imploring the graduates to be the next great generation that they're (destined?) forced? to be.
"...they said that white Americans weren't ready for an African-American, but they
were; they said that young people would talk a good game, but they wouldn't get
their acts together to register and then to vote, but you did. The experts knew
things, but they didn't know today's Americans, and they certainly didn't know
your generation of young people."
I particularly like the bit about taking time to loiter and let your mind wander. Disconnect.
