My mother sent me to see a doctor on a snowy day.

I was dizzy and fell feebly on my mother's warm back. I remember when I was a child, my mother's back was so broad and strong. Now, my mother's back has become thin. My mother bent down and hurriedly carried me on her back. She kept looking up at the traffic in front of her, walked for a while, then stopped, helped me up, and gasped and continued to rush to the hospital. It is still raining. Thin raindrops fall on mom's hair, forming round, crystal clear dew, which is beautiful. But mom has no mind to pay attention to these. A cold wind blew and lifted mom's hair. A few dazzling silver hairs suddenly appeared in front of my eyes. They bared their teeth and gnawed at my mother's youth. How can I stop it?
