unmistrusting:

listen. hogwarts houses but instead of placing all the houses in the same dormitories you place them in mini dormitories that each have a Gryffindor, slytherin, ravenclaw and hufflepuff

that way when these 4 kids eventually become friends (and lbr they will after basically living each other after 7 years)

all these personality types are evenly balanced out. when the Gryffindor wants to be reckless the slytherin is like ok chill or we could think this through. when the ravenclaw devotes too much time to studying the hufflepuff is like or you could care abt urself too

and etc

this way ur chances of having 3 reckless Gryffindor children trying to save the school every year dwindles js
