I want it

We are so like children. As soon as someone tells us not to do X, we want to do it with a passion. Even in the best scenario we are at least curious. This spill right over into how we deal with relationships. If we are interested in someone and they show us too much attention, we don't like them as much. They don't show a lot of attention we begin to question ourselves. Somehow we become intrigued. We probe a little. Consequently, investing more time into them. It's like we are trying to prove that we are at least up to par to any standard you may have. This leads to game playing. "You can't call for 2 days" (despite the fact you are dying to call). Why all of the games? Why do we want the things we can't have? Why are the things we can't have more appealing to us? Is it the challenge?
