The quiet kid/little king is having troubles dealing with life and its issues. He feels lonely and hopeless, but at the same time don't want to worry/disappoint a close friend or family member; that's why he can't send them Christmas cards (that are usually happy and full of all the promising things that happened during the past year) and is isolating himself from them. Even though he knows you could never tell if you really know someone and all the things they are going through, he wishes there could be more emotions and less politeness and formality.
