"I admire your courage, Boldness, intelligence, beauty, refusal to conform to others definition of traditional beauty, your kindness, loyalty, love of family , great mom skills, fashion sense , work ethic , activism," the family matriarch continued. "I could go on. It's one story I will tell . The Asst. principle called me when you were in the 6th grade and said you started a petition to discipline a teacher because she continuously allowed a student to harass and disrupt the class and keep the other kids from learning! She said you were disruptive and too grown, at which I said "go Solange." I was as proud as I could be! I told her so. You were always lite years ahead of your time. We are always here and got your back!! I love you with all my heart!!!"
