I couldn’t read it either, but I figured that it was a note saying that her father/other important male figure in her life passed away. I don’t really think you’re supposed to be able to read it. The video is basically about how Christina’s father used to take her to the circus when she was a young girl, and she dreamed of performing in it. Now, when she is older, she becomes a famous circus performer. She gets caught up in her career, and this creates a bit of distance between her and her father as she grows up. She wore an elephant necklace that he gave her when she was a young girl, and at the end, she realized just how much she loved him after she gets the news that he passed away. Ahhh.. makes me cry everytime. Hope I helped.
