I'm not really a "dessert" kind of person. But when I do, which is a rare moment, I eat chocolate cake if there is any.
If humans are your enemy? Are you an enemy with yourself? So, when your system is feeling good you try to be sad?
We're all enemies to ourselves at our darkest times. And no. Why would I force sadness when my system is good? That wouldn't make sense. Or perhaps it does to some people *psychologically speaking*
