What's the first thing you can't say casually about small things?

Once a friend of Yu Youren wanted to ask him to write a poem, but he couldn't say it directly, so he held a banquet to invite him to drink. Yu Youren really went to the appointment happily. After three rounds of drinking, Yu Youren got drunk and fainted in Tao Tao, so his friend leaned down and asked him to write a picture for himself, so that he could frame it and hang it on the wall of his new house.

Yu Youren was drunk at this time. He picked up a pen and paper, wrote a line with great momentum, and then fainted. My friend was very happy, but when he held it over and looked intently, everyone on the table couldn't help laughing. It turned out that Yu Youren got as drunk as a fiddler and wrote a warning sign "Don't pee anywhere". Friends can't laugh or cry, so they have to put them away in the cupboard.

The next day, when Yu Youren woke up from a hangover, his friend told him about it. Yu Youren stroked his beard and leisurely asked his friends to take out the words. After his friend did what he said, Yu Youren thought for a moment, reached out and cut the inscription into several pieces, and then put it back together in different order, from "Don't urinate anywhere" to "Don't be casual in small places". My friends couldn't help clapping their hands and admiring them. They thought it was wonderful.
