The negative - positive energy is just a believe system.
Can you imagine how hard would be living in a system like that?
What if "negative" means different things to different person.
Like for example a guy dress in a peculiar way, too extravagant, and that's positive for him, but his sister thinks he's aweful because people stares at him, and that's negative for her? And she wears only what other people thinks is good.
If a parent was meant to enforce the positive, which one would he reward?
Probably both, but he would have to explain why, and main point is there is no absolute positive or negative side. Only sensations and perceptions.
