Why does the old man have to walk home all night when he comes back from the countryside to buy food?

A deaf-mute father took a bus from Qiaokou Chang Di Street to Xinzhou Yangluo, and missed the last bus when he came back. The thrifty old man didn't want to stop taking a taxi, but walked nearly 40 kilometers overnight. He came home yesterday morning, and his wife, who had been scared up all night, cried with joy.

At 3: 30 am yesterday, Chen, who lives in Huai 'an Yili, Chang Di Street, Qiaokou, called the news hotline for help: her 76-year-old wife Liu went out after lunch the day before yesterday and never came home. Liu's father is deaf and dumb, with a height of 1.75 meters, a square head, neither fat nor thin, and wearing camouflage clothes on his upper body.

The 70-year-old mother-in-law Chen has inconvenient legs and feet and can't go out to look for it in the middle of the night. "Dad is deaf and dumb and can't hear the car horn." Worried about his wife's safety, Chen sat at home talking to himself, so anxious that he could not sleep at all.

Yesterday morning, the reporter of Wuhan Evening News contacted Chen for the first time to inquire about the situation. She said excitedly, "Dad got home safely at 6: 25 in the morning, and thanked the newspaper for its concern." What makes Chen Mei think is that Liu's father actually came back from Xinzhou Yangluo. Chang Di Street is nearly 40 kilometers away from Yangluo, and Dad Liu walked all night.

Dad Liu came home hungry, tired and exhausted. Chen quickly heated a bowl of rice for him. Dad Liu took a bath before going to bed.

It turned out that Liu's father heard his wife say that the food in the country was cheap, so he took a bus all the way to Yangluo. He didn't buy any food until dark, and he missed the last bus back. Dad Liu walked back along the road until dawn.

Chen said that dad is not without money, but she knows that his wife will not spend money on taxis. He has been accustomed to thrift all his life. When his wife returned safely, Chen's hanging heart was finally put down. When she was happy, she nagged Liu's father again. Liu's father told her by sign language: I will never go so far again, and I will never do such a dangerous thing as walking in the dark again.
