You can find out what type of person someone is by asking them "What does a bandage do?"

If they say something like, "Oh, it keeps the blood from getting on things." Then they think more of their surroundings.

If they say, "It protects the wound." Or "It helps keep the blood in." They think more of the injured person.

If they say, "You know what it does, dumb*ss." Then maybe you should rephrase the question.
