I don't like my weak self

There are fewer stray dogs these days, but there were quite a few when I was a kid.
I also have scary memories of dogs coming into the elementary school grounds and following me all the way back while leaving school on foot.
Let's assume that you just happened to run into a stray human rather than a stray dog.
Maybe the high school in the neighborhood is a Yankee school, and it is a “generous” school that accepts many Yankees who had no place to accept them in other cities and towns.
Also, it may be an atmosphere where your own appearance and clothes are easy to lick.
There is a high possibility that even stray dogs will run away if they see a lion.
Why don't you have your family take a video of yourself walking and facial expressions and take a look at it?
I received job interview training when I was a student.
What was pointed out by the teacher acting as the interviewer at that time was that “if you keep your mouth ajar, you look sloppy.”
I was conscious of not losing my smile, and I dared to show my front teeth, but that had the opposite effect (probably looked stupid).
Incidentally, after that, when I was conscious of the muscles around my mouth on a regular basis, I felt that my face became slightly smaller (my lips were thin). The face is also a muscle, so you can train it.
So, there are people who are easily licked due to their appearance or habits, so let's check them out.

I read it.
There was such a terrible thing, wasn't it? You're still having a hard time not being able to forget that. I don't know the details of the situation or those people, but I understand your painful feelings from the bottom of my heart.
After all, I think it's a crime. If even the slightest bit of such a terrible thing happens, let's call 110 as soon as possible. Then, let's have police officers clearly arrest people who have done such terrible things, let them be punished, and ask those of you who have been harmed to apologize in good faith.
Also, ask the school, board of education, and parents to take strict precautions through the police station, and ask them to be thorough so that they never commit the same mistake again.
Your heart must have been deeply hurt, so please speak clearly and slowly to your specialist and counselor about your painful feelings. And please relax your mind.
I sincerely pray that your heart will recover first, and that such a terrible thing never happens again.
And I wholeheartedly support you and your child.

I listened to your story.

I read it too and it made me uncomfortable.

They imitate hitting their precious child while raising a strange voice, and laugh at it with their peers. As a parent, it's natural to feel unforgivable.

Even after a year,

“Why couldn't I do anything at that time?”
“Why didn't you go to the police box right away?”

It's probably going to come back to mind.

But first I want to say it.

It's not that you couldn't protect your child.

Suddenly, 4 or 5 male high school students showed up and acted unexpectedly. Everyone's body hardens for a moment in such a situation.

Later, I think “I should have done that” no matter how many times I want.

But I couldn't do it at that moment.

There's no need to keep blaming it.

Moreover, luckily, the young lady was hardly aware of the act.

I think that was really a relief.

I also contacted the school.
I also consulted with the police.

It's not like you haven't done anything.

Unfortunately, now that more than a year has passed, in a state where there is no evidence and the other party cannot be identified, it would be difficult in reality to pursue responsibility at that time.

That's why

Rather than blaming yourself in the past, decide what to do the next time the same thing happens.

First, ensure the safety of your child and yourself.

Take distance.

Record and record from a safe place with a smartphone or, if possible, with a long recording that can be clipped on.

The date, place, number of people, clothes, characteristics, etc. are also recorded.

If necessary, call 110.

Recordings and videos can be used as evidence, and are also useful for subsequent consultations with schools and police.

However, what is more important than anything else is

It's safer than evidence.

You don't need to approach or talk back to your partner to record.

and

“I did what I could at the time. Next, I'll record and video and talk to the police”

I think it's okay to go that far and make a break.

Your daughter is with you now.

The next few years and decades we'll spend together are far more important than the few seconds in the past.

Please don't blame yourself.

You did such a violent thing, didn't you? The people themselves were probably “just kidding” from the fact that everyone around them was laughing, but the side where that fist was pointed is terrified, isn't it? It's violence, right?

The student's behavior and the school's response are unfortunate. It's frustrating, isn't it? There is no place to sue anymore. The police couldn't prove it with just your story, so they probably couldn't move.

This kind of trouble is lurking close to us, and it is necessary to “raise your voice” and “hold back evidence.” However, for victims, how frightening and courageous it is. Crying and falling asleep also happen.

You're still traumatized by that frustration, aren't you? Chagrin is also about one's own actions, right?

Even so, protecting the child and appealing to the school is a courageous act. The results weren't what you expected, and your feelings probably wouldn't clear up, but even so, you acted at that time. Why don't you acknowledge yourself like that?

There were more things we could do... that is probably something we can only think of later.
If that's the case, I want you to make use of this experience without ending with this. Anything is “consulting with the police,” “recording,” and “consulting” about how to move. That heart hurts, and it will protect you and your loved ones.
