You were Mammon's kid and no one messed with you because of being the son or daughter of the sin of Greed. And you and him were playing around and you wanted to do his makeup and you did! It took a long time and you put a lot of glitter on him and you were finished and you handed him a mirror and smiled at him and he looked at himself.

“I told you we needed more glitter...” He said in an annoyed tone. Not at you, at himself for not getting more glitter.
