Someone of the male persuasion (doesn't have to be related) who you are very close with. Someone whose opinion and insight you value over anyone elses. Someone that you desire only the best for them in life with no strings attached. Someone who has impacted and influenced your life for the better.
I'm not related to David, but his thoughts and opinions are very important to me. He's a brother that I look up to.

Brothers can be fun but also complete assholes.
