Something is up. Sam is Quiet!

Ok I don't know if i'm just getting paranoid or something but i'm beginning to think that Sam is up to something. hummm but What? I have no idea. My son is quiet today. Yes.... Quiet! He's not Sick. Thank God. I think he's just found something to keep himself busy today or something. He'll run into the living room or kitchen and get something to eat or whatever and then he's off again. I just can't get over the feeling my son is planning a revolt or somthing. kinda worrying here.
