children's thoughts are relevant

The world is kind of awkward. Why do we have to say "we are okay" when we are not okay. Why do adults consider children's feeling as insignificant and something that they will eventually get over. It's sickening. I say that because I have seen such cases. Parents consider their children immature and that they'll eventually grow up. To me, it sounds almost like they are brushing off their children's thoughts at that certain age. But to their children, that thoughts of their are very much true and realistic. To quickly dismiss their children's emotional state is wrong. I can't specify what I am talking about, but I hope I am making some sense here.
