you are wrong and ive linked evidence/studies earlier in this thread that agreeYou're wrong. You can be addicted to anything. Its not the activity itself, but the way they make you feel. So while its possible to quit it, its hard due to the fact that the games make them feel better in someway. Its an emotional and psychological addiction. Its a very real thing. We are seeing more and more evidence of this. Times where people quit work to play a game. Times when people revolve their entire life around what goes on in a game. Anything you revolve your life around to such an extreme can be an addiction. You can break these addictions much easier though since they are on an emotional level. Often times by finding something else to fill that void and help you keep away from it.
That said, this is poor parenting 100%. They obviously had some indication that she was sneaking around. They should have punished her hard for the first time, and harder for the second. That system should have been removed after the second time she did that. The fact that she had such ample access to it to begin with shows that they don't care to be a part of her life enough, and now they toss her in rehab instead of dealing with it.
