That's my head teacher

Two days before the final exam, Su Mobai decided to take off Lin Tianhan's vest first, and then find a chance to have a good talk with him.

But how to make it reasonable, Su Mobai was worried about this, but these two days are also very busy, so Su Mobai had to pass the final test first.

The final exam was obviously stricter than usual invigilation, and Su Mobai did not bring food into the classroom anymore.

Fortunately, Su Mobai once invigilated the mathematics exam, so he could do it with these students at that time.

On the second day of the exam, there was mathematics in the first class, but because the second year of senior high school and the senior high school had alternate exams, the exam started at nine o'clock in the second year of senior high school, which prevented Su Mobai from waking up early and rushing to collect the papers.

When he went to get the papers, Su Mobai asked for a spare paper first, otherwise there wouldn't be one left for him to do after the exam papers were handed out.

Su Mobai finished the paper in [-] minutes. He didn't write the detailed process for the big question, but just wrote the idea.

Su Mobai started to feel bored after finishing the papers, but the students in the examination room were quite peaceful and did not cheat when he invigilated the examination.

Su Mobai walked away for a while, then walked around the classroom again, and the time passed like this.

After all the exams were over, Su Mobai called the classmates to the class assembly, and then handed out the homework for this winter vacation.

Su Mobai didn't assign them extra homework, and he also knew that if there were too many homework, these children couldn't finish it, so they made up their minds to copy homework.

The next day, Su Mobai saw that there were not many students in the first and second grades in the school, and only the third graders were still fighting in school for the college entrance examination.

After the third grade exam, the school finally became quiet. Su Mobai was used to going out for a walk after dinner, but he was not used to seeing the deserted school.

"Ms. Su, aren't you going home again this year?" The security guard who was rooted in the school locked the school gate, leaving only a small door for one person to enter and exit. When walking around, he ran into Su Mobai.

"No, uncle, when will you go to your brother's house for the New Year?" Su Mobai never told anyone about his birth, not because he didn't want to, but because no one has ever paid attention to it.

"The day after tomorrow, I see you have been here for two years, why haven't you come home! Did you quarrel with your parents? Oh! This is a good communication with your parents, we are all one family." The security guard also felt strange, Su Mo Bai didn't go home for the Chinese New Year two years ago, he just thought that Su Mobai must have quarreled with his family.

"Without uncle, I have no family." Su Mobai did not say this directly.

"It's all my mouth's fault. Remember to treat yourself well during the Chinese New Year." The security guard heard the meaning of these words, and he blamed himself for talking too much and asking too many questions.

"It's okay, uncle, don't lock the door by the way when you leave, I won't be able to get out then." Su Mobai quickly changed the topic and made a little joke.

"I won't do that. I'll put a key under the stone in front of the gate. Do you want to take one too?" The security guard also remembered this, and was still a little worried about whether to lock the door.

"No need, just put the key under the rock." Su Mobai didn't know what his plans would be, and he wasn't sure if he would go to him, so he didn't take the key.

When it was dark, the two of them went back to their residences.
