Smiley, you are so correct! Speaking the truth in love is what is important. I had someone, one of my instructors in Bible College years ago, said that if someone would throw medication at him, he would throw it back. But if someone would hand him medication, and he needed it, he would take it. This has a lot to do with attitude and love expressed. Someone who is dishonest is not a friend. A friend finds a way to speak the truth even if it does hurt, but being very careful how that is done, because there is no cause for dealing hurt to others purposely.
Tact is important, which means using the truth with kindness, not hurting feelings. I probably should tell someone how fat they are, even if they are fat, and if discussing weight is important, there should be a kind way to deal with the subject. Maybe someone has poor taste in clothing, or color matching and schemes, but there is no doubt a kind way to deal with that.
Be careful with people's feeling, and be kind, and have a heart when dealing with people. Put yourself in their shoes and decide how you would want to be talked to or treated. We all need love and understanding!
