1.Hatred all video games. Especially those with even an ounce of violence in them. (This includes Hello Kitty Roller Rescue, because nothing teaches violence like watching a cat wack blue blobs with a little yellow mallet on roller skates.)
2. Fear of facts. Even if the book is right in front of you.
3. No respect for anyone else's opinions or beliefs other than your own. (Coincidentally, the KKK hold the same view.)
4. The only people you associate with want nothing to do with you and/or are ignorant parents who cant figure out that it's their responsibility what their kids play.
5.Every time you try, you fail. And fail some more. Then you blame it on someone else.
