我们为什么要上学？

Hello, everybody! Thank you. Thank you. Thank you, everybody.

All right, everybody go ahead and have a seat.

How is everybody doing today? (Applause. ) How about Tim Spicer? (Applause. )

I am here with students at Wakefield High School in Arlington, Virginia.

And we've got students tuning in from all across America, from kindergarten through 12th grade.

And I am just so glad that all could join us today.

And I want to thank Wakefield for being such an outstanding host.

Give yourselves a big round of applause. (Applause. )

I know that for many of you, today is the first day of school.

And for those of you in kindergarten, or starting middle or high school, it's your first day in a new school, so it's understandable if you're a little nervous.
