Why does 'being bad' feel so good?

Mostly, we are all brought up to be good boys and girls, so why do we all feel tempted to walk on the wild side sometimes?

When we were asked by Mark to contribute something we felt we had done that was 'bad' there were no shortage of takers. Most of the contributions weren't really so bad - a bit foolish maybe - but that's about all but would we have told our families, those deep, dark secrets? And if our parents had been asked the same question, what do we think they would have submitted?? Probably, much of the same.

I think we have to feel tempted by the 'bad' stuff to be able to understand the good. After all who wants to be vanilla all of the time?
