A dressy couple is standing in the lobby of an apartment building. The man is scanning the list of names on the directory, looking for the right button to push.
"Is my dress OK?" asks the woman.
"Your dress looks fine," he responds without looking at her, still scanning the list.
"Does my hair look all right?"
He looks at her and pushes a button. "Your hair looks fine."
As they are buzzed into the building, her voice floats back into the lobby. "Do you have the slightest idea what my hair looks like when it does not look all right? Do you have the ability to identify that particular state of being?"
