I have a brother. On the surface, he seems to
have nothing in common with me. That is, he
doesn't in any way resemble me in appearance.
What a lucky man he is.
From when he started to live by himself, I make
it a rule to drop in on him about once a week
and eat out with him. And during supper, we
talk a lot about many topics including our old
days.
Through this experience, I've gradually noticed
that we brothers have in common that having to
do with personality―that is, both of us are
very poor at interpersonal communication. Brother
pointed out that poorness at communication to this
degree is exceedingly rare―according to him, less
than 1 out of 100―and the fact that both of us
have such poorness is almost miracle.
I agreed with him in that point. To be explained
in terms of home ENVIRONMENT, or to be genetically,
that is a question.
