We all need friends.
"One who has unreliable friends soon comes to ruin, but there is a friend who sticks closer than a brother." Prov 18:24
Most of us have a circle of friends. Often times, our friends will have the same passions, be from the same socioeconomic backgrounds, and share our same interests. Some things may be slightly different, but for the most part our friends would think along the same lines as we do. After all, if our upbringing was from a conservative Christian environment, we probably wouldn't be close friends with an atheist, for example, for the simple reason of avoiding offenses against our beliefs.
