Amy burns Jo's manuscript

Little sisters can be pretty annoying, can't they? Always messing with your stuff and hanging around and getting on your nerves and all that. I know that Amy annoyed Jo sometimes but I never saw her annoy Meg or Beth nor have I seen Beth annoy Jo or Meg nor have I seen Jo annoy Meg but I guess that when older siblings tease and provoke their younger siblings like Jo does to Amy, it makes the younger siblings like Amy want to get in their older siblings' hair like Jo's, doesn't it?
