Children might leave out details in a story because they simply forget them. Their young minds are still developing memory skills, so it's easy for some parts to slip their minds.
In many cases, it's a good idea to leave out the ending. This gives readers the chance to form their own expectations and keeps the mystery intact. But for some novels where the ending is unique or sets the story apart, a hint might be okay.
They wanted to leave everything behind and go out for a walk. This feeling expressed their boredom with their current life and their desire for freedom and adventure. People hoped to leave the familiar environment to explore a new world and find inner peace and satisfaction. This kind of talk also reflected people's yearning for nature, hoping to personally experience the beautiful scenery of the mountains and rivers of the motherland. The expression of this kind of mood could be to relieve one's stress or to look forward to the future. Whether it was walking alone or wandering with friends, it was all for the pursuit of inner freedom and the meaning of life.
One way is to ask them specific questions about the story. For example, 'What did the main character do right after that?' This makes them think back and include more details.
