I was 4 in 1997, I learned from my mom about Princess Diana, my mom told me about a beautiful british princess who was very kind and was loved by everyone, after that conversation with my mom I started to read everything I could about her, she will be missed forever

It's been 22 years this year since she was killed and i still miss her, she was so kind and helpful to the ones in need.. may she rest in peace ..

Diana was a most beautiful lady. It still saddens me to think she is no longer with us. She was someone you will always miss. I still want to cry. We do not understand why things happen the way they do. But one day we will. To God be the glory.

Yes her death was suspicious. The one thing that haunts me is the fact that she said they would someday kill her.
