the angels were wearing white clothes and each child carried a candle (蜡烛). He noticed that one child's candle was not lighted (点燃). Then he saw that the child was his little girl. ______ he rushed to her right away and put her into his arms. He kissed her and then asked, "Why is your candle alone unlighted, darling?" "Daddy, they often light it again, but your tears always put it out." Just then he woke up from his dream. The lesson was clear, and its effects were quick.

The father was too sad to communicate with others and to do anything. | ||
