I've heard so many different versions of it, that I don't believe any of them actually happened. NOT THAT THEY COULDN'T.
As a general rule, if the story doesn't come with a source, it's not worth passing on, especially if touted as actual events.
But of course, I applaud the actions of this mythical 11-year old girl.
I also take a dim view of propaganda (even if based on actual events) that tells me what kind of person I am based on whether or not I instantly agree with it and pass it on or not.
