This is a case of a wise mother sitting down with her child and explaining the situation to them. Tell the daughter/son that the ill child may never have the same opportunity again as her child will. Tell her that she has her whole life in front of her to enjoy such pleasures, whereas the ill child may not reach their next birthday.
Ask her to make this one sacrifice for the sake of the other child. Never scold the child for her jealousy, but explain the situation in a calm and loving manner.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
