What should I do with this woman's broken mouth!

God, such people are rare! In order not to hurt your feelings, you can also talk to her in turn! For example, you said driving before, and she said that. You can also smile and say, "Oh, yes, I'm really worried that I'll bump into you one day" and the subsequent exam events. You can also smile and say, "God, I'm afraid that will disappoint you. I think only people like you will fail the exam. Oh, I'm super lucky now, hehe. . . "In fact, I was trained, and so was my roommate. . You should also give her a taste of cold jokes, so that she will always feel better.
