2017-12-08 ""A couple flirting" is the subject of the greatest possible protection" [長年日記]

"I feel uncomfortable seeing "a couple flirting"in the public place, such as in a train."

If you have some hypotheses that can be explained logically, please contact us.

By the way, as I was a young person I've been an experienced "couple who is flirting", so there is no problem to exclude the hypothesis that " my jealous" for a couple who is flirting.

If possible, I would be happy if you could discuss it from a "behavioral economics" point of view (now it is my boom).

From the viewpoint of "selfish genes", I examined it (but the logic collapsed).

-----

Given the current declining birthrate and Japan's aging population,

""A couple flirting" is the subject of the greatest possible protection"

However, the psychology of us seems not to act like that.

During the busy year-end, I know that it is troublesome for you, however, please give your support for me.

Furthermore, if you send me a impressive hypothesis, I will give you the honor(?) that it will be introduced in my blog.
