We must not discuss our secrets with our friendsWhen I was a child I read somewhere in any book that we should not tell our secrets to our close friends provided that we don't want our secrets be known to other people. Initially I didn't understand it because of being a child but later I realized that my close friend who did I talk freely with would discuss all our talks to his other friends. Although it's not an issue of disclosing any secret of mine, it's simply an alarming bell for me and it was inculcated in my child brain to keep my tongue in control while talking with my close friends.
Also those people who always take interest in backbiting of others should never be chosen for friendship because if they can discuss shortcomings of other people with you, undoubtedly, they will discuss your shortcomings with other people as well. I consider them as anti social elements. Their presence in your circle is also harmful.
