Returning a Father’s Love
He was a single father, raising a 5-year-old boy by himself. He often worried about his son growing up without a mother to care for him.
One day, he went away on business, leaving the child alone. He worried about his child all the way, not knowing if he had eaten. But his child always told him not to worry. He went home after he finished his work.
When he got home, the child was deep asleep. He was tired out. He was about to sleep when he was surprised to find an overturned (翻到的) bowl of noodles under the quilt (被子). He hit his sleeping son angrily, “Why are you so careless, making the quilt dirty?  Who will wash it?” It was the first time that he had hit his boy after his wife’s death.
“Sorry, but…” the child explained with tears in his eyes, “This is your supper, Daddy.” In order to let his father eat dinner when he arrived home, the child prepared two bowls of noodles: one for himself, the other for his father. He was afraid that his father’s noodles would get cold, so he placed them under the quilt!
Hearing this, the father felt deeply moved and felt sorry about what he did to his son — he hugged his son tightly without saying a word.
