There was once a very old man, whose eyes had become dim, his ears dull of hearing, his knees trembled, and when he sat at table he could hardly hold the spoon, and spilt the broth upon the table-cloth or let it run out of his mouth.
“It’s okay, maybe a plastic bowl would have been better.”
His son and his son's wife felt empathy at this, so the old grandfather was put in the best seat in the house.
'What are you doing there?'
“I am going to make a sculpture, to look at when I am older to remember how you treated grandfather, and I will do the same to you.”
They gave him lots of food, and when he spilled, they helped clean it up. His son and wife both took turns to help him eat. Things such as guiding the spoon to his mouth, serving him the food, and even making him whatever he wanted on certain days of the week.
One day, the mans frail and weak hands could not hold the bowl, so it fell to the ground and broke. His son and wife quickly gathered up the shattered pieces of the bowl and threw it away without hesitation.
One day the little grandson of four years old began to gather together some bits of wood upon the ground.
When the son and his wife turned old, the little boy remembered how they treated the grandfather and they were treated the same by him.
