Friendships are essential to living a happy life in my opinion. Friendship is something that requires hard work and dedication but the pay off is huge. I honestly don’t know where I would be in life right now without my amazing, loving and caring group of friends. They are my backbones and my biggest supports (besides my family of course). Friendship is honestly one of the hardest jobs in the world, because friendships require a lot of effort in order to maintain them. Both parties in a friendship need to work hard at them or else they will wind up drifting apart. 
One of the closest friendship I have read in a piece of writing was the relationship between Dionysus and Vlepo in Frenzy by Percival Everett. The two had a dynamic that was so enjoyable. Dionysus had created Vlepo for himself, because I think even gods needs friends, even if they were self created. Vlepo showed loyalty and trust to his “friend” Dionysus. The god often sent Vlepo into situations were Vlepo had to report his experiences. Dionysus trusted Vlepo in order to report exactly what had happened.
Trust is an earned and not given. I trust my friends with my life. I have had friends who I mistrusted with my belief that they would always be truthful to me. But over my life, I have realized even if telling the truth could possibly hurt your friends, they would rather be hurt for a little than repetitively lied to by someone who they thought they could trust.
