Bill was walking through the hallways of his school, bored because he had physics class, which he hated with all his being.

Right at that time, every Friday, the younger children left school, so Bill would watch them leave before going to his physics class, because he had nothing better to do. Among the children leaving school (between 6 and 8 years old), there was always a boy carrying a Hello Kitty plush. Bill found it curious and adorable.
