A recent feature by Sue Doyle discusses the importance of letting a child from the ethnic community know that he is going to face sarcasm outside his community. The sooner a child's parent prepares or equips the child to deal with the bias outside the community the better it is. The parents should prepare their children in accordance to his or her psychology.
For Sue it was her grandmother and she is thankful to her as she says:
As a child, I'm not sure I can say I completely understood. But, now that I am an adult, I can honestly say I am very thankful to her. When I did encounter prejudice and hate, it didn't come as such a surprise, first of all. Then, rather than interpret it as something wrong with me, which a child might very well be inclined to do, I recognized it as something wrong with other people's logic, something with our society. And my grandmother's wisdom and support empowered me to take constructive action rather than bottle it up.
