he put a pen cap into his mouth.A few minutes late, he was terrified to find that he had

swallowed it!The teacher was shocking when the boy stood up and said, "I've just

swallowed a pen cap."He was quickly sent the nearest hospital.There a doctor examined

his and said the best treatment was to take some medicines so that the pen cap could pass

natural.Three hours later the boy successfully made it."She is really lucky, " said the doctor.
