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.

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.

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

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.
