Last Friday, I was playing basketball with the friend on the court when I accidentally hit a passed student with the ball. I felt terribly and immediately apologized him. He was in pain and I knew I have to do something to help him. I offered to walk him to the nurse office and waited with him until he felt well than before. I was also carried his books and accompanied him for the rest of the day. I learned that in the future however happens, we should take responsibility for their actions and make things right.
