Have you ever taken a joke seriously on April Fool's Day?

There is an April Fool's Day at school, just before we finish the test. After class, I was sitting in my boring seat reading a novel, and then one of my classmates rushed into the classroom and came up to me and said, you didn't do well in the exam. If the teacher asks you to go to the office, you may be criticized. I know today is April Fool's Day, so I think this classmate must have lied to me, so I said I don't believe it. You must have lied to me on April Fool's Day, and that classmate was caught. While we were talking and laughing there, the head teacher came over and motioned for me to go out with him. As a result, my grades were really poor, and it was really a coincidence for the class teacher to know what the reason was. Since then, I have been careful every April Fool's Day.
