The last question of the afternoon was "Alex from Boston", who thanked his girl for being "my best friend" and then popped the question. This turned out to be something of a setup; Alex is Warren Buffett's great-nephew. But the arena still broke into hearty applause.
Normally I'd add, "I hope she said yes". But this is a relative of Warren Buffett. I'm sure he knew the answer to the question before he asked it.
