I wouldn't mind if someone didn't want to donate their money. If it's yours, you have the right to do whatever you want with it. However, I think it's incredibly rude to automatically assumed that these unfortunate people would not donate if they had the chance as some or most definitely would. Hopefully one day she'll realize how important and life changing generosity is.
You can never, ever get anywhere purely on your own. Not to mention, her reaction to this 'internet fame' which will soon die out is disgusting.
Hopefully we can all learn a thing or two from this.
