Make up a story with grandpa, granddaughter and donkey.

Grandpa took his granddaughter to sell donkeys. On the way, grandpa felt his legs were sore and sat on the donkey's back, followed by his granddaughter. Pedestrians on the road have accused: you see the old man sitting on the donkey's back alone, but his granddaughter has to follow him. He really doesn't cherish children. Grandpa immediately got off the donkey and put his granddaughter on its back. After a while, another pedestrian commented: You see that little girl is so ignorant that she let her grandfather follow her, which is unfilial! Grandpa was helpless and walked on with his granddaughter in his arms. Just walking for a while, I heard pedestrians say: Look at them, they don't ride donkeys, how stupid! Helpless, grandpa sat on the donkey with his granddaughter in his arms ... Finally, the donkey was exhausted. ...

This should be wrong ... but please adopt it.
