If you smoke in the school toilet, the security guard only smells smoke when he comes in, and there

If the security guard came to the toilet before you came in and there was no smoke at that time, and then you came in and the security guard went into the toilet again and found the smoke and no one else entered the toilet during this time, then he would only arrest you without evidence. If it weren't for the above, then he wouldn't be able to catch you. You don't have to have a cigarette butt to catch you, because the cigarette butt can be washed away at any time.

If the smell of smoke is pronounced.

You can even see the feeling of smoke.

Of course, there must be someone smoking in there.

All you have to do is prove your innocence.

As for the farewell.

It's better to be free.

Because after all, he is to maintain public order.

Smoking in the school toilet and being caught by the security guard for smoking no one has evidence, but you are indeed a student and you are still a student, be honest and don't let you smoke, it's for your own good,

Are you offending anyone? I don't usually do this kind of boring bad guy thing

You didn't draw it, you can declare it to the school.
