Many years ago, there lived a poor man who had only one son. One day, there was no more money or food left in I the house, so the man said," My son, you must go to find some work and earn some money."
    The young man left home. He walked many miles until he met a rich farmer who had thousands of sheep. This farmer needed a shepherd to look after his sheep so he gave the young man the job.
    There were seven mountains around the farm, and there were sheep in every field on every mountain. One day, black clouds gathered. A storm began. The wind tore off branches and blew down mighty trees. The rain poured down. Paths and bridges were washed away.
    The young man rushed around and gathered the sheep from the seven hillsides to lead them to shelter in the farm. He had almost reached the farm with his enormous flock when he saw that the bridge over the last stream had been washed away. There was only a wooden plank left.
    It was only safe for the sheep to walk across the plank one at a time. They did not like the look of the narrow, creaky piece of wood, but the shepherd pushed a big black sheep across and the rest started to follow, one at a time, one at a time.
    What happened next? I’ll tell you when all the sheep are safely across the plank. At the moment they axe still going over, one at a time, one at a time, one at a time.
    Have all the sheep crossed over the bridge yet? Oh dear me, no. The young man saved thousands of sheep from the mountains and fields. They all have to get across that shaky plank, and they are still crossing, one at a time, one at a time. When will the last sheep have crossed? You may well ask. The answer is, they will all have crossed when every sheep is on the other side! But just now, they are still walking over, one at a time, one at a time.
    And what about the young man? Well, he is still waiting, and watching those sheep crossing the plank, one at a time.
    One at a time, one at a time.
