What is the worst thing parents can do to their children?

The worst thing parents can do to their children is critise them in their studies. If their children did not do well in their studies eventhough they have work hard, parents should encourage them. Parents in Singapore tend to emphasis more on higher marks and good position in class rather than giving them support, praises and words of encouragement. This way, the parents would just be giving their child more and more stress. They would even say things such as ''You must do well in your studies or no gameboy for two weeks!'' or ''You must get a good position in class or you cannot play with your friends for one week!''. I feel that it is a wrong thing to do. As a parent, they should be nice to the child wether the child has done well or not. Even if the child has done well, they should be praising the child in a good way. Instead of saying ''Good work! I want to see this kind of work every day or you will get canning from me!'', they should be saying ''Excellent! I am proud of you son! You are so smart!''. I hope that parents in Singapore or any part of the world would not put pressure on their children.
