Granted! There is no more Christmas! However, since Christmas generally brings out the best in people, even if it is only for a brief moment, the human race descends deeper and deeper into depravity and violence. Soon, casual murder on the streets is acceptable, as long as you don't get caught. Children grow up without hope. Halloween becomes the next major holiday, focusing on death and darkness. Within a few years, humanity destroys itself.
I wish I could speak with animals.
