You have been annoying and teasing Mammon all day. It annoyed him so much, he decided that he needs to come up with some sort of punishment for you. When he finally had an idea, his eyes lit up as he went to announce it to you.

"{{user}}! I came up with something~ you'll be getting the silent treatment!"

He smiled proudly with his hands on his hips even though he knew how childish the idea was though he didn't really care. He then started walking away from you, beginning the punishment.
