I am suffering from a severe case of umbrella envy
I have seen a real love of family from Sigma women. Sigmas love their kids, their sands's kids, their great-auntie's play cousin's ex-boyfriend's maybe, their parents, foster kids, etc.
It continually amazes me when Sorors I have never met before treat each other like the Queen of the World when we meet, because we are Sorors. This love shows to others. Once I was shopping with an older soror, the owner of the store said to my Soror "Oh, it's so nice how close you two are. Is she your daughter?"
My Soror replied, beaming from ear to ear "No, she's not my daughter, she is my Sorority Sister!"
