Being a human, you gotta do what humans do. You walk, you eat, you communicate. Human stuff.
You're walking down a street and notice a dog, it's cute. You want to say hi to it, and so you move towards it. It moves towards you. You're both moving towards each other but wait.
why is the dog barking? why does it look angry? what did I do wrong?
The dog comes at you faster giving you lesser time to process. The dog knows batman is invincible with prep time, so it removes the prep time.
