  • One of Obama's keywords.

    Last week, I heard a conversation in the train: a man asked a woman (who was reading The audacity of hope) about that word. He didn't know its meaning.

    Was it a good choice for a politician's book title, then?

  • It's a pretty common word. I'm surprised the man didn't know it.

  • Especially if he was interested enough to pick up the book...

  • Perhaps not a good choice for a politician, but a good choice for a leader.

  • Sounds as though the woman was reading the book and the man asked about it, no? Either way...common enough word.

  • Oh. Sorry, I got that wrong...
