Why did you go to that person for advice?

Have you ever notice the persons we choose at times when we made or want to make certain decisions in our lives? Why do we often seek advice from the person who would support our wrongs?

• You break up in your relationship and you speak to the person who never like your spouse or someone who have always told you to break up with them. Are you expecting good advice, really? 
• A person on the verge of backsliding hardly ever speak to a Christian, instead he speaks to one who has also backsliden or persons who are no longer in church to gain support for the reasons he/she is backsliding. The reasons include the people in that church are hypocrites or feel they are better than everybody else. Funny enough these persons never choose to attend another church.
• A young person never go to the one who told them they are too young to have a boyfriend and to study their books. No! They go to  their peers most times, who say things like "man gone and man dey" or willing to listen to who other girls the man was seen with or if he has a vehicle and buy her nice things.

I have often been in conversation where the person speaking really does not expect you to go against them. They want to hear they are right to embarass the man in front of his friends, to curse their relatives or put them in their place, to walk out of their children's lives and leave them to their father (his turn now), to skull school and go visit their boyfriend, to carry clothes in their bags to go out because their parents are not giving them any freedom and the list could go on. As soon as you try to show them the wrong in their 'right', you are no longer a good friend. It makes me wonder, what makes a friend good? Maybe you can help me here.
