I'm sure I'm not the only American radio listener who has this experience while driving. I'll listen to the BBC World Service, and my mind will start to wander. Ten minutes will go by, and I'll realize that I don't remember a word of what I've just heard.
And yet, due to the gravity with which the news was presented, I'll still feel informed. Hours later, I'll hear news or an interview regarding that same topic, and I'll think, "That sounds vaguely familiar. I remember hearing something about that, I think, on KWMU."
There's nothing like feeling faintly informed about the world around you.
