A dark horse I have known

I will introduce a dark horse I have known in this blog.  The person is my younger sister.  The reason why is that she did not pass the university entrance exam that she really want to go, but as a result, she got a chance to study there as same as other students.

Actually, she had taken various type of entrance exam many times for half a year to enter the university, but unfortunately she could not pass them.  In addition, all tests were gone, so she decided to go another school that she had already obtained admission. However, she suddenly got an acceptance letter from the school before five days when the entrance ceremony is held.  The reason why is that a student seemed to quit to study in the university, and she could have a chance instead of the person.

Anyway, she was so lucky, and no one expected about that.  But, I am sure she has something special ability at important events in her life.  It is not only this case.  I think we could say she is a dark horse.
