Invigilator

One day, Feifei, Linlin and Jingjing three small mice rushed to finish their dinner. Jingjing said: "We got up too late this morning, the school gate was closed, we didn't catch the exam, we had to make a test at night. Feifei said: "We don't know who the invigilator is!" Lin Lin said: "Take him, it's already seven o'clock, let's go!" said three little mice striding to the school. . When they first entered the examination room, they ran out in panic and ran wildly in the direction of their home. Do you know what this is all about? Haha, the invigilator of the original examination room is a cat!
