After work, my colleague invited me to be a freight elevator, but the leader found out and fined me. What should I do?

The leader has repeatedly stressed that all employees should not be late for no reason. But I was late many times, especially the day before yesterday, and I didn't ask for leave from my superiors. I feel particularly guilty about leaving early without permission from my superiors, which has had a bad influence on all employees. I think it is necessary to tell the story of leaving early the day before yesterday. The story goes like this: the day before yesterday, the company leader stipulated that our first group 13:00 would be on standby at the company, and I 12: 45 would arrive at the company. The team leader took us to the sixth floor to find the highlight of Wang Hai to give gifts. After confirmation, we delivered the gift to our new cinema and gave it to Huang Zhenxing. After the gift was moved to the second floor, the team leader was responsible for keeping it, and Xiao Xie and I were responsible for pushing the trolley back to the company and giving it to the members of the second group. After returning to the company, take a break and open the movie ticket by the way: it says that the activity time is 15:00 to 18:30. I thought that if I waited until the end of the activity, I wouldn't catch the last bus, and I didn't prepare anything for my dad (dad's birthday). So I was weighing these two things, and what should I do to kill two birds with one stone: it won't affect the organization of the company. I didn't delay my father's birthday. Just when I was thinking hard and couldn't figure out why, I saw Manager Lu rummaging in his seat. It turned out that his movie ticket could not be found. Suddenly I had a brainwave: I could transfer the movie tickets to Manager Lu and ask for leave by the way, which not only solved his urgent needs, but also achieved the effect I wanted, so I did it. Manager Lu didn't agree at first. When he really can't find it. So I agreed. In fact, I only told manager Lu what I was responsible for, for fear that manager Lu would disagree, and I didn't tell him the part where I moved the gift and went back to the cinema to help maintain the work order. Therefore, it should be my fault that I lied to General Manager Lu before he allowed me to take time off. Although I know this behavior is wrong, I did it anyway, so I think it is necessary and I should do it to the leaders. What I have committed is a serious matter of principle. I know the leader is angry and disappointed at my absenteeism for no reason. I also know that it is the most basic responsibility and obligation of the employees of the company to ensure that they obey the company's schedule, do not leave early and do not miss work. But I haven't even done the most basic things. I thought calmly for a long time afterwards, and I gradually realized that I would pay for my impulse. The serious expression is still in front of me, and I am deeply shocked. So far, I have deeply realized the importance of the matter. Now, the big mistake has been made and I deeply regret it. After a profound review, I think there is a fatal mistake hidden in my mind: my ideological consciousness is not high and I don't respect others enough. I will show more respect to the leaders in the future.
