In the book Totto-chan, Takahashi was short, but no one talked about it because they probably didn't realise that he was disabled or had faults. They just accepted him as a child.
When we grow up, we know more, we know the faults, we know when one is disabled and when we see that, we even stop feeling pity for them! That is why our brain cannot use it to its total capacity because the more we know, the more problems we create. Life will unfold itself. We don't have to force it to open its destiny.
In an extract from Peter Pan, Peter says to Wendy: Children don't believe in fairies because they know more than what they are supposed to know, and that's why fairies are fading from the world.
Accepting people is looking at their good qualities, not at their faults, because after all, everyone is different and no one is perfect.
