How can a girl's stomachache make her happy?

If you are by her side, cover her stomach. Of course, I remember that the temperature of boys will be half a degree higher than that of girls. If you are not hot yourself, there is something called a hot water bottle. And if she doesn't remember, you should remember to put the medicine in her bag (mainly because there are fewer boys with bags). There is also to help her, gently pinch the meat between her thumb and forefinger, so that her stomach will be much more comfortable (my mother taught me). Buy some soda cookies for her to keep. More importantly, buy her a thermos. So if she has a stomachache at night, she won't miss warm water. What's more, don't be stingy with good words. People always want to be comforted when they are uncomfortable. It might be better to comfort them. If it hurts all the time, it may be worse. Take her to the hospital. Tell more jokes. People are happy, how can their stomachs be unhappy? Aha!
