Leng Bingling asked anxiously, "grandma, what happened?"

Wu Shuang said, "it's no big deal. I woke up and took a nap to take a walk home in the Central Park. When I met an electric car, I turned to the car and didn't see the road. My right foot accidentally stepped on a small pit and sprained my foot."

Leng Bingling was startled by Grandma's words. She shouted "ah...".

Wu Shuang said, "Why are you yelling so loudly? When I sprained, I just met Xiao Lu and went to the Central Park. He went home on his back. When he came home, he also covered my ankle with ice. Then soon, the doctor he called came. The doctor said that there was no big problem with minor injury. Tomorrow, it should be able to reduce the swelling and walk on the ground without pain."

Leng Bingling just walked into the living room and saw Lu Tianyu. She was angry and didn't notice her grandmother.

Now she saw that grandma sat on her side on the sofa, raised her right foot and put it flat on the sofa. Her naked feet had been wrapped around her ankles and feet with bandages and fixed with medical tape.

She threw the schoolbag on her left shoulder heavily on the floor, hurried to Wu Shuang, squatted down and said softly, "grandma, why don't I go to the hospital with you for another examination."

Wu Shuang waved his hand, "Hey! You know I'm most afraid of the smell of medicine in the hospital. Just now Xiao Lu said to take me to the hospital. I wouldn't go. He just called a doctor to check me at home."

Wu Shuang lifted her right foot. "You see, it's all right. It's just a little painful and swollen. Xiao Lu has applied ice for me just now. It's much less painful. The doctor said that if the swelling is reduced and the pain is reduced tomorrow, you don't have to go to the hospital for examination."

Lu Tianyu put down his tea cup. "Grandma, the doctor said that ice should be applied again in about 2 hours. Ice should be applied to sprain within 24 hours, which will help reduce the overall swelling and bruises."

Wu Shuang looked at him kindly and said with a smile, "I see."

Leng Bingling glanced at Lu Tianyu, who knew a lot.

She pursed her lower lip and threw two words to him: "thank you!"

Lu Tianyu's lips were slightly raised, "you're welcome."

Wu Shuang said, "Alas! I only care about my foot when I come back. I haven't cooked yet. I'm going to cook now." looking at Lu Tianyu, "Xiao Lu, I'll go after dinner tonight."

Leng Bingling frowned slightly: dog classmate, I rubbed you another meal.

Her eyes turned to grandma's feet. She was injured and wrapped in a bandage. She could stand. She quickly said, "grandma, your foot is sprained. You can't stand to cook, or I'll do it!"

Wu Shuang raised her hand and rubbed Leng Bingling's head. "You've never cooked. Can you eat the food you cook?"

"It's all right. Just sit in the living room and give me directions."

Lu Tianyu stood up and said, "I'll do it!"

With that, he went to the kitchen without waiting for them to agree or not.

Wu Shuang said, "Xiao Lu, that's funny! Every time you come to my house, you have to cook."

Lu Tianyu: "grandma, I have to cook at home. There is no difference between doing it here and doing it at home."

Wu Shuang asked incredulously, "aren't you cooking with your parents at home?"

Lu Tianyu looked at Wu Shuang and said with a smile, "my parents are abroad. I live near the school by myself. When I get home from Monday to Friday night, I basically cook by myself and go back to my grandfather's house on weekends."
