Everybody has their thing. Even if I can never understand why someone might do something depending on what it is I just have to respect that.
A while back I watched a movie about a man who explored caves got trapped and died. Then I watched a documentary about people who rock and mountain climb. Some of them without safety ropes.
It's some shit I would never do or understand the joy these people get out of it but I respect the simple fact that it's their thing and it ain't really harming anybody.
