Did you enjoy yourself yesterday? I suppose you did. But I’d like to tell you how a bad day I had yesterday. Nothing just went wrong. In the morning, my alarm clock didn’t ring, so I woke up an hour late. I was in such 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 discover that nobody was there. The school was quiet but peaceful. Our classroom was locking. I realized in that moment: It was Sunday.
