yes, absolutely agree they are hard nuts. Base on
my contact with them they are very good in creating something out
of nothing for nitpicking and always insist they are right and
others are wrong.
There was once both the chinese ed and I were chatting happily
and suddenly she dumped a bomb to me. Out of no where
she accused me an English ed for siding England just because I am
English educated. To me, that was absolutely uncalled
for. The TV programme she used to nitpick at me was not even
related to her faultfinding.
usually, I will cut people of this category off. I
have no interest, no time to spare to interact with them.
The inward looking and the often like to compare with others set
them out like sore thumb.
