Answer: The Miller has his son climb up on the donkey with him
Step-by-step explanation:
In the short story of The Miller, his Son and their Donkey, a man and his son keep listening to the opinions of others until the donkey drowns.
If the main problem in the story had been that the Miller needed a job and worried about the opinion of others about him, it would make sense why he kept listening to various opinions, one of which was when he told his son to get on the donkey alongside him when people had criticised him for riding on it alone.
