forgiveness，happniess，mistake，
Forgiveness is an important character of people. In our whole long life， we are impossible to make no mistakes or do nothing wrong. Therefore， it’s essential for us to be tolerant. Everyone deserves a second chance when he or she makes a mistake. Forging others sometimes is forgiving ourselves. Keeping something unpleasant in mind does no good to us. Letting the unhappy matters go brings happiness and pleasure back to our life.
