Now I am on the Yokohama Municipal Subway and head for the Proving Ground office.

In front of me, there are three foreign grandmothers, mothers, and children who brought a baby stroller.

I think they are "Russian" because of the words they are talking about.

The mother and child suddenly started a conversation using their smartphone Skype.

The conversation partner was like their father.

In Japan, the use of telephones on trains and buses is a violation of manners (?), however, there is no clear reason to explain why it is a violation of manners.

After all, manners are basically in a different dimension from logic, so explanation is not necessary.

For example, "Do not speak loudly in art museums" is a manner based on the premise that many people enjoy art quietly.

The same reason can be given for "Do not rub pasta" and "Do not make up on the train", but basically it seems that "discomfort" is a prerequisite.

For example, I don't feel uncomfortable just about "make up on the train", however, I know that an overwhelming number of people feel discomfort.

Aside from that.

This is also often said that it seems that humans feel uncomfortable with conversations that only hear "one of the conversations".

Today, I was able to hear the other party's voice on Skype.

I also feel that the conversation on the train is "uncomfortable", but I realized that the discomfort is much reduced when I hear the voice of the other party on the phone.

So why don't you try a social experiment called "Unlocking smartphones with hands-free mode only for a limited time"?

For example, we only need to create one "hands-free mode conversation-free" experimental vehicle.

I would also like to get into that vehicle.

Next to "Women Only Vehicle", I think that making "Smartphone Conversation Free Vehicle" is a pretty good attempt.

Anyway, about this talk, I want to believe that

"I couldn't feel uncomfortable because I didn't understand Russian at all"
