Now let's talk about the dark side of the world. At some point of the kid's life, we need to show them the complete truth of this world, including the dark side: the jungle aspect, selfishness of human nature, the firceness and ruthness of the competition, etc.
Now the question is when and how we introduce this concept to kids. At what point we should do this. Should we start with the bus riding, it seems too early, but I can see that some parents are already start doing it...
To live well in this world, we can not be always nice, we need to be tough and ugly sometimes, our kids need to learn this skill..
any child psychologiest here :)
