In my opinion, sisterhood is unconditional love between two or more women. Not necessarily related biologically, but something deeper more innate. A bond that cannot be expressed with words or pagentry, but something as comfortable and familiar as a mother's love. It is the ability to communicate without words. Not having to "entertain" one another, but just being in one anothers company and share time for quiet reflection and ntrospection.
Sisterhood is a rare phenomeon and should be treasured like precious jewels (pearls preferably)
