I've just seen a TV programme about those girls on German television, and got curious - so I googeled.
I think that those girls are two of the most outstanding and remarkable persons I have ever heard about in my life! While people like us are not able to cope with let's say minor problems, they face something that none of us could ever imagine, everyday - and they still live a happy life!! I think this is something we all can learn from - we all have so many things to be thankful for, sometimes we all should concentrate on things that really matter - and not loose ourselves in things we tend to make up ourselves!
I am not Christian and was not brought up to believe in God or some sort of creator - but those girls are the living evidence that there is something out there. Whatever it was - something just made them so special to send a kind of message to the world - that's what I think.
All the best for you and your parents as well,
Charles
