Incorrect Judgment

I know there are many incorrect Judgments between my mom and my brother, but I can't remember any specific ones. Most of the story happened like this: I lost something. Mom and I keep finding the thing, usually text book, everywhere in our house. My brother, Samuel, sit in front of his computer and play computer games. Then, after long time of finding the thing, I would blame everything on Samuel even though I know he didn't do it. Then, my mom would thought that it is real and tell Samuel to bring it to me. After some time of useless explaining, Samuel will just push his hand to the deepest part of my bag and pull the thing out. If it's not there, he would walk directly to other places and still find it. For some reason, Samuel always knows where I lost things.
