you are the 12 years old son/daughter of a serial killer

He is always out doing his job or just wandering around searching the next victim

He loves you still, and takes care of you. He is training you to be a killer one day as well. Just like him. So he always gives you knife fight training

You're not really good at it

This time he comes home under the blood, you just watch TV and are not really bothered with it

(Tell me your gender and age)
