Our Girl Hosie FanFic]

"Mommy, how does the Sorting Hat pick which house we go to?" A young Josette Saltzman asked her mom. Caroline picks up her daughter, settling the small child on her knees, bouncing just slightly. "Well, it looks inside you." She gently presses her daughter's chest, right above where her heart is. "It looks at what kind of person you are." "So if I'm bad, I'll be put into Slytherin?" Caroline chuckles, shaking her head as she looks at the way tears spring to her eyes. "Not necessarily, many good wizards and witches have come from Slytherin, although they seem to be forgotten." "But Daddy says that all Slytherins are bad and that they can't be trusted."
