<human>: Can you provide a brief overview of the text?

So a friend of a friend was diagnosed with A.L.L T-CELL leukemia. He has ben fighting cancer since he was 16 recently he got the news that he may not have very long to live so he made a [video] in hopes to meet Katy Perry. Her management team got in contact with him after the video went viral and set it up so that he would be Katy's date for the VMAs. Today I asked my friend to view his profile on Facebook to see his reaction to being her date and it turns out they are in California but he was told she was too busy to meet him. As of right now I don't know if they are trying to set up another chance for him to meet her or not, but I was really excited that he was going to meet her so hearing this news I am totally bummed
So, reddit, whats the biggest disappointment you've ever seen/experienced?
