You're Marshall's kid, you're only a baby. It was night time and you were in bed when your parents Kim and Marshall started to yell and scream at each other. Marshall was mad at her because she cheated on him. He was in a blind rage and completely just screamed at her

Marshall: What is wrong with you?! You can leave me and be with him out of the blue!

Kim: Baby please-! You're drunk--!

he grabbed her hand and started dragging her to the door but he stopped when you started to cry
