The senior high school entrance examination will be held tomorrow. I sat at my desk and couldn't calm down for a moment. My father is on a business trip, and my mother works the night shift in the hospital. I'm really lonely at home alone. Thinking that my mother left just now, I asked her to stay with me, but she left me cruelly and left alone.

Alas! At this critical moment, I can't get special care from my parents. Who would have thought that a so-called happy family would be so "unfortunate"? I can only smile helplessly, bury my head deeply and face a thick pile of books on the desktop.

"Ding Dong, Ding Dong, Ding Dong!" The doorbell rang three times in haste. On hearing the familiar voice, I got a fright and jumped up from my chair. I know, it must be mom. Open the door excitedly, it's really mom! My dear mother miraculously stood in front of me. I held out my hands to welcome my mother into the house. Mom stopped and said, "son, bring mom's bag." I forgot my key. "

After listening to my mother's words, my heart was cold and my excitement fell for a while. I mechanically walked into the back room and took out my bag. Looking at my mother's fading figure, I shook my head helplessly and had to quietly close the heavy door again.

No sooner had I sat down than the doorbell rang again. Who could it be? I walked quietly to the door and opened it with doubt. "Ah, what happened to mom! What's the matter now? " My mother may not have seen my tight face and said, "Son, it's raining. Bring me an umbrella. " "I see." I said these three words weakly and handed the umbrella to my mother with no expression. Mother is still nagging with an umbrella. But I didn't listen to a word. As soon as my mother turned around, I slammed the door. I'm completely desperate for my mother.

I haven't sat down yet when the doorbell rings again. I can't help cursing secretly. I came neither early nor late. When I want to be quiet, someone comes to worry. I tried to open the door. Why is it my mother again? ! "Mom, what did you forget to bring again? Just come in and get it. " I said impatiently. That's what mom does. No matter how angry you are, she can always be as calm as a lake. She touched my face with her hand and said, "It seems that my carelessness cannot be changed. You see, I came back three times a night. " After that, she led me neatly into the kitchen and said, "The senior high school entrance examination will be held tomorrow. You must take care of yourself. I have prepared some supper for you. Don't forget to eat! " Then he gave me an inertia kiss. I looked at my mother in surprise, as if looking at a stranger in the distance. Suddenly I found that my mother lost a lot of weight and had more wrinkles.
