One winter night, a teacher was on her way home. Suddenly she fell down from her bicycle in front of a car. The driver stopped his car right away and brought the teacher to a hospital nearby.

"The patient's name, please?" "What's the problem?" "Are you her relative?" … The nurse asked quite a few questions. But the driver answered nothing. He then quickly disappeared.
…
In the end, however, the teacher still saw the driver.
