Problem-solving ideas:

When thinking encounters special obstacles, you must quickly leave your accustomed thinking and look at it from other aspects. Let’s think about the problem, for example:

Mom, dad, son, daughter, housekeeper and dog, go for an outing together. When they reach the river, they have to go to the other side. There is only one boat. If the mother is not here, the father will beat the daughter, and if the father is not here, the mother will beat the son. , the dog will bite if the housekeeper is not around! I would like to ask: How should they get there?

If you think too much about how to live, or dwell on the question of who is grouped with whom, then you will be completely confused by the question, and the answer is to find another way.
