Wishful thinking would be weed+music.
Realistically, The human race would help each other by getting attack from something out from space. Even if I hated the human next to me, saving the human race is more important. I also think we would win a battle or two.
Even if the world flood, I don't think humans will help each other. Hopefully humans can prove me wrong if it ever happen.
Late night thoughts. Goodnight and I love your face
