But some people are hardworking and lazy, some people change quickly, and some people are too lazy to move. Who is the most diligent to return clothes first, and who is the laziest to procrastinate? (The hardest worker is 2, and the laziest one is 1, because if you don't do it, you will never stop. )
As soon as they came out, everyone stared at each other's clothes. 1 and 2, what color do you wear? Who wears the most fancy and bright clothes? Who wears the ugliest clothes (1, 2: 1, green 2, white 5, 6: colorful 7, 8: messy)
They finally set off, but when they arrived at the door of the teahouse, two of them were gone. Which two are missing? (Throw 3 and pull 4)
When the two men catch up, everyone will sit still. Who must be sitting next to 2 (1 and 5: because no three no four)?
10 Who must be sitting next to it? (8,9: Because 89 is close to 10)
Everyone sat down and found 2, 4, 6, 8, 10 sitting on one side. Please type an idiom. (coincidence)
The boss finally brought tea and everyone began to drink. In the process of drinking tea, who drinks the most intently and who drinks the least intently? (The most attentive ones are 1: single-minded, and those who are not attentive are 2 and 3: half-hearted. )
Who is always told what to do? (5 and 6: Wu Yao drank 6 cups)
Finally, only one person finished drinking tea. Which one is it? (gulp it down)

Parents divorced, husband and mother got married, and the mother's name was added to the real estate license. My husband divorced my mother again.
