Russia case...

That terror case in Russia is really a nightmare to everyone. I noticed one news. A mother was bringing her 6 years old daughter to the school with her 2 years old son along. Unfortunately all 3 of them were trapped in the school stadium by the terrorists. But then the terrorists decided to let the mother go but she can only choose to bring one child with her. She has chosen to bring her son away and let her daughter cried sadly behind her.
I really wonder how the mother made the choise. Because the boy is still young? Or maybe just because that is her SON? I thought only we chinese prefer boys than girls.... Fortunately the poor girl was saved at last. She was saved by a 15 years old boy. She told the boy, "Please don't leave me alone..." This was what she said to her mother 24 hours ago. But her mother left her back yet the boy brought her ran out from the school with him.
I am thinking, how will the girl think about this? Her mother chose to give her up at the moment when she needed her most. I am sure that she will ask herself, "Why mummy chose brother instead of me?" If I were her, I think that I will become emotinally unbalance. I think that this will leave some negative effects for her psychology development. Poor girl....
I can understand that how difficult the mother has to make the decision. Why doesn't she choose to stay back and let both her children go? It's really for a mother to choose between her children. Lastly she chose one, another one is considered to be abandoned... Will she regret for her decision? How is she going to face her daughter in future? When the girl grow older to think about this incident, will she hate her mother or maybe her brother?
Sigh.... Life.......
