As usual @chbartist Sir, the way you articulated about this very important trait has to be applauded and you have explained it plausibly!

"The only difference that they have is how much they are truly in control of their vulnerabilities and how other people can use those mentality holes to hurt them....

A brilliant, noteworthy point @chbartist Sir. Of course, we must NEITHER suppress NOR encourage it too much. According to the situation, the vulnerability factor must be increased or decreased. IF WE GO FLAT IN ALL SITUATIONS, OUR LIVES WILL ALSO BECOME A MERE FLAT WITHOUT ANY PROGRESS IN THE FORWARD DIRECTION!
