Did you enjoy yourself yesterday? I suppose you do. But I’d like to tell you what a bad day I had yesterday. Everything just went wrongly. On the morning, my alarm clock didn’t ring, since I woke up an hour late. I was in such a hurry that I burnt my hand when I was cooking the breakfast. Then I ran out of the house to catch the 8:30 buses. This is the bus I usually take. But, you may laugh, I missed it of course. I am very unhappy, and scared as well because teacher hates the students coming late to school. So I ran three miles to school only to found that nobody was there. The school was quiet but peaceful. Our classroom was locked. I realized that moment: It was Sunday.
