Often women are far more willing to talk about psychological topics
than men, but there are also men who are very open.
Also when others tell about certain situations one learns about
different attitudes of people.
Especially younger people are often feeling strange around other,
older people, because they do not have that much experience with the
"inner life of others" yet, which can make them feel insecure.
But there might come a point where - though in another way and
differently expressed - they realize that we are all "cell-bunches
that walk around" having many alike emotional programs in the
basolateral part of the amygdala and in the hypothalamus,
and that if something happens to "tilt some of such programs out of
balance" many people struggle to balance them again
but often go a wrong way;
and the older you get the more you might realize HOW many.
Many people are a bit nervous, but a lot just don't show it.
But if you know what to watch out for, you usually still see.
A friend of mine said he always was very nervous, until he observed
the hands, voices, posture, bragging and masks of other people
and came to realize that many are nervous, too,
and that the more he focussed on that, the calmer he became.
