@isiben Real friends are actually rare. When you find one,you'll definitely know cause they wouldn't mind if there is anything to lose. Their focus is adding values to the other person which also includes constructive criticism.

I remember a quote"Better lose a friendship than lose a friend".
Meaning If telling you the truth would cost me our friendship,it is better than to cost me a friend's life. Later in life, the friend will realize.

Better have one sincere real friend than a thousand for-the-moment friends.
