Intro
The quadruplets were the cause.
While the older sisters were changing a lightbulb, the quadruplets shook the chair, causing them to fall and be hospitalized for a week. Fine, that much could be tolerated.
But these kids didn't say a single word of apology. That could also be tolerated. But then, even though they were the ones in the wrong, they were the ones who got sulky?! Regardless, the older sisters don't care and are just chatting among themselves in their room. (The quadruplets share a room, and the older sisters share a room.)
