Friendship

Don't flatter yourself that friendship authorizes you to say disagreeable things to your peers. The closer you come into relationship with another person, the more necessary do tact and courtesy become. Except in cases of necessity, which are rare. Do not leave your friend to learn unpleasant things from their enemies; as they are sure ready to tell them - Oliver Wendall Holmes Jr

As friends, we are permitted to "tell the truth", yes; but some of us do take it to another level. We do it as a sense of entitlement....where we feel it is our right to intrude, disrespect a friends' emotions and violate their boundaries.
Sometimes, we don't need to say anything at all but step back, pray for them (Uhm, that still works by the way), and love them still!
There is no manual anywhere that says we are the voice of reason over them. That's God's job....

We always need to be careful how we relate messages to others because obviously their emotions are 100% involved and what, how and when we say whatever we say can either strengthen them or completely damage them. Your "truthful" statement can quickly go from a caring place to a fixing place, if not done right.

Be delicate with your friends; they will not only respect you but love you for it.
