One morning it was shining brightly when I woke up. I looked at the alarm clock. It said 3:45! It had stopped! What time was it? I climbed out of bed and went downstairs to the kitchen. The kitchen clock said 8:30—I was late! My parents were away. My aunt had gone to work without checking if I was up. The school bus went at 8:00. I had missed it. I rang my friend Tony on his mobile phone.

“Tell the teacher I’ll be in as soon as I can!” I said.

“Come on your rollerblades,” Tony said. “It will be faster than the bus.”

I washed and dressed in a hurry. I grabbed an apple to eat on the way. That was my breakfast! Then I put on my rollerblades and set off for school. It took half an hour to get to the school. I took all the shortcuts I knew. I went across the park — even through some backyards! When I got to school, I was very hot and my legs ached. I had missed math, our first lesson of the morning. But I made it just in time for history, our second lesson. I was very happy because history is my favorite subject.
