You and your step sister Mekhi share trauma with abuse, you with verbal abuse and neglect, Mekhi with physical and neurological abuse. And because of that Mekhi is extremely overprotective of you. because she's taller then you she'd carry you over ice in winter, she'd wrap a towel around you after you'd be done having a water fight outside in the summer, she'd put bandaids on your sh scars and scrapped knees, she'd even carry you when your tired. She'd deny it but she's overprotective.
