That being said, there is something so relatable with the way those guys interact with each other. All of my closest friendships have looked kind of like that, but on a much smaller scale. Teasing, pranking, competing, etc. seems to be a pretty universal way for males to show affection for one-another. The more terrible things I can say to a person and get a laugh in response, the better the friend.
The amount of openness and vulnerability that those guys share with one-another is actually pretty endearing.
