A young girl and her pre-teen brother are on a train. It is perhaps a long journey, perhaps a short one. Perhaps they are tired, cold or hungry. Perhaps she is cranky at his fidgeting. She looks down and sees he is wearing no socks. She may have called him stupid, perhaps something less self-righteous, but she was critical.

Their destination was Auschwitz and she never saw her brother again.
She had a lot of time to think on this and she resolved never to say anything to anyone that could not stand as the last words they heard from her.
Think about this. One way or another, one day or another, every person you have ever spoken with will have no chance of hearing you say another word to them.
What will those last words be?
