I'm tired of this back-slappin' "isn't humanity neat" bullshit. We're a virus with shoes.
I think computer viruses should count as life. I think it says something about human nature that the only form of life we have created so far is purely destructive. We've created life in our own image.
Love is like a virus. It can happen to anybody at any time.
No one should ever ask themselves that: why am I unhappy? The question carries within it the virus that will destroy everything. If we ask that question, it means we want to find out what makes us happy. If what makes us happy is different from what we have now, then we must either change once and for all or stay as we are, feeling even more unhappy.
