The last time I let the talent scout have one of the children when my family was poor, there were more than one of them with a serious/grave sickness and I had to choose between having them pass away or sending one of the children away.
Life is full of decisions and I find that a lot of children want to feel as though they can make a difference for their family. I know I did! I wouldn't want my daughter or son to feel as though they have to provide for me, it just happens in life sometimes.
