Further along in the letter, she gives the girls individual attention.
To Beyonce she wrote, "I wish people could see how you are when you're not in front of the camera or on the stage. How compassionate and kind you are to people, how you look them right in the eye when you speak to them. How hard you work, how generous you are with your time and money. How you don't care if anyone knows about it because you do it from the heart."
For Solange she shared, "I knew when you were born three days late that you would walk to the beat of your own drum. You were always my rebel warrior! Always defending the underdog and fighting for what you believe in. I remember you, at 10 years old, started a petition to remove a bad teacher, and your dad and I were so proud of you. I love that you do not let others define who you are, or what you are."

About Kelly she wrote, "I know without a doubt that you were a true gift from God. You came to live with us when you were only 11 years old. You were the sweetest, most kind person I had ever met and you still are. You are also a true survivor. You never give up. Your discipline and drive always inspires me."
In writing about Angie, she said, "You were always so mature, always challenging me and questioning why. (Fortunately I never believed in the "Because I said so" or "I'm the adult" crap, either.) I always trusted that you would look out for and protect Solange, Kelly and Beyonce, and you did! You still do sometimes."

In closing, Tina wrote, "I'm often asked, what was my most proud moment? I would have to say it was at my recent wedding, when all four of you said in your own words that I taught by example and that I helped to make you the women you are today!!!! That was truly my proudest moment!"
