Susan Cheever loves her for that. And so do I.

You see this picture of Senator Clinton? If you lived under a rock and didn't know who she was, you might think that she was a middle-aged business woman, taking care of business.

She's well-groomed, if slightly gray. She's wearing her glasses (the better to see you with, my dear), and she doesn't seem to be all that into smiling pretty for the camera.

This is because she's wearing her thinking face.

Which is not a bad expression to see on the President of the United States, in case you've forgotten.

Susan Cheever's Why I Love Hillary as heard on All Things Considered Wednesday.

Ms. Cheever probably has a thinking face, too.
