Rejection is a big part of show business. It can be tough on anyone who doesn't have fairly good self-esteem. Especially kids, as they try to discover who they are.
We live in an age of instant knowledge. And there's almost a sense of entitlement to that.
Above all, though, children are linked to adults by the simple fact that they are in process of turning into them. For this they may be forgiven much. Children are bound to be inferior to adults, or there is no incentive to grow up.
