How can I confront him? If whining and complaining were an Olympic sport, he would win. He whines and complains until he gets what he wants whenever I want to do something. He's the king of being annoying, just like Suri Cruise. I have to deal with his constant complaining and "I want this. I want that. I want to watch this. I want to watch that. Bla bla bla." How can I confront him while being polite at the same time?

All I hear is " I wanna do this. I wanna do that."
