Blood counts for a lot I totally love my close fammily, but much of my extended fammily and tribe are more likely to make my blood boil.
I have sworn many men as brothers, though we share no physical blood line… we have shared our blood together many times for a cause or struggle. Hence I have “brothers” and “Sisters” who are as loyal if not more so than my real siblings.
In Islam every Muslim is my Borther and Muslimah my sister… and likewise as a Human.
But sometimes brothers have to kill thier fellow brothers so whilst it is thicker than water all things can be diluted… 
Betrayal is another thing i fear and hence while i trust many… i depend on none.
Besides our people dont always let the oldest take the mantle… so sibling rivalry, and inter-fammily fueds are a constant problem.
Thank Allah I have put the last of my fammily’s bloody feuds to ground for now. But after me who knows… a life is a fragile thing.
