It's very difficult to say 'no' to children. They can look so crushed and disappointed. Their woeful little faces tug at your heartstrings.
Many parents feel like ogres when they are forced to lay down the law.
They feel like the villains who have taken the sunshine out of their children's lives. But unfortunately, life's like that. It isn't all fun and games and doing whatever you want. And the sooner children learn this, the better. Naturally, the people elected to bring this home to them are their parents.
