One afternoon Mary and her little brother Tom were playing hide-and-seek in the street just outside the post office.Mary had closed her eyes when Tom found that the door of the letterbox had been opened.The postman had just taken all the letters out andgone into the post office.Tom climbed into the letterbox and closed the door from the inside.When he knew he couldn't get out,he became very afraid and began to cry.
At the same time,Mary was looking for him everywhere,but she couldn't find him.Then she came back to the letterbox,and heard her brother crying in it.She ran to tell the postman.
With the help of the postman,Tom got out of the letterbox."Next time if you want to play hide-and-seek,don't hide in the letterbox."
