Was it a button to look at other people's thoughts... I think there was a cartoon like that.

There was a scene where the main character of the cartoon threw away the device (buttons?) because of a wound he suffered while looking at other people's thoughts, so he didn't want to look at other people's thoughts anymore. I didn't understand it at all, but even in my childhood, I thought, "Why do I throw away that treasure box for that reason?"

And seeing people reading other people's thoughts and pouring out hate for each other at Tapgol Park, I now know why. Sharing each other's thoughts can bring progress to someone, but someone has confirmed that they are different from me and found that hate can sprout. Social life, in which you wrap yourself up and act with a mask, tries to maintain a polarized situation.

I'm not good at it, but I'm trying to act similarly by learning it as I get older. It's much better than at least 20 years ago, so I can do social life or something. On Facebook, however, each person's thoughts are intentionally or unintentionally exposed. When you see the thought, you know that it is different from the other person you imagined, and if it touches your own standards, a line that causes a certain disgust, you hate the person himself.

There is so much hate in the world.
