"How could one who has all the opportunity to be Royal bring herself down to show the rest of us her heart? I will always be grateful for your way of showing us what class is really about ... Most of all I will remember the beauty in your soul."
"She is gone and no one will change that. Sure... She was attractive, famous, and still a young woman. So what... why make such a big deal about Her death? Hundreds of young people die every day and nobody gives all of them even a fraction of the attention they give Her. Are they worse than She was? Hm... I don't think so. Why shouldn't we let Her rest in peace and get off her back for good."
Tomasz Grzesik, Chicago
"She had everything. That is what we thought. But, sadly, happiness is something that can't be bought. She had more than her share of personal sorrows, but that sweet smile never left her as she dreamt of better tomorrows. And in her world of unseen stress she tried so hard for that bit of elusive happiness. To add to her misery, was the hounding by the press. Laying bare her smallest actions for the world to see. Now she is beyond all that and at last free. Rest in peace sweet Princess Di."
V S Shirali, Mahim, Bombay, India
"You never say goodbye to someone that you love; you just say, I will see you tomorrow, for life on earth is so long there is no time in Heaven... I know that you and your family will be in my prayers for some time to come. So I shall say, I'll see you tomorrow my sweet Princess. May God Bless and Be with You All. 1 Thessalonians 4:13-18."
Lauri Stanger, Sheridan, Wyoming
"She did so much good, so many simple things a Royal would never do. She showed the world that she was a great soul. She has been quoted as the "Queen of Love" and the "Queen of LIFE", for no one shall forget her. My thoughts, prayers, and heart go out to her children in this time. Words cannot express what I and the world feel. She lives on in our hearts and dreams, and through her life... ours is better."
Mark Bailey, United States, Vermont

Carla Acera, Covina, California
"My heart goes to the family and friends of such a beautiful woman! I only wish that I had personally known her! I treasure her as I do Jackie Kennedy! Both wonderful women! Diana is in my prayers! Now she is finally at rest and at peace! May she rest in the peace of Christ! I think of the song "Bring Him Home" - change the words to "Bring Her Home"!! God love her."
