     Today was not a good day. Everything went wrong. First, I slept late and Mom shouted at me to

wake up.        

     When I went to the kitchen for breakfast, there was nocereal. I decided to have some toast instead,

but I burned it. I had to eat it anyway because there was no more bread. There was no juice, either. I

just had a glass of water.        

     When I was almost at the bus stop, I realized that I had forgotten my wallet, so I had to go back

home and get it. Of course, I missed the bus and had to wait for the next bus.     

      I was late for school and the teacher told me to stay in classroom at lunchtime to catch up on the

schoolwork I had missed.    

     After the lunch, it was time to give the teacher our homework.I reached into my bag to get it but it

wasn't there. I had left it at home. I was in trouble again.      

     When I got home, I went straight to my room to catch up on my homework. Mom cooked fish for

dinner. She knows I don't like fish, but she thinks it is good for her son. It was a horrible day. I hope

tomorrow will be better.
