All schools have their own rules. The rules change from one school to another. Some schools are much stricter than others. There are also some rules that are strange or funny to us. Here are some funny school rules: Strict Japanese rules Most schools ask students to wear uniforms, such as sports suits or skirts. But Japanese schools even have rules about the colour of underwear ! They also require  that girls' socks should be folded  in a certain way and boys' heads should be shaved . Other Japanese schools tell students that they can't go to the movies after sunset. Different shoes in the USA At some American schools, students have to change their shoes when they go into the schools every day. This makes sure students won't fall over on the floors and keeps the schools clean. No strange hair in the UK Strange hairstyles are not allowed in some British schools. But they might allow students to wear certain hairstyles during the World Cup years. There were two students who had special hairstyles during the 2002 World Cup. After the World Cup, their teachers asked them to go to the barber's  at once. Why do students in the USA have to wear indoor shoes?
Because in that way they won't hurt if they fight. Because in that way they will feel comfortable. Because in that way they won't fall and can keep the schools clean. Because in that way they won't make any noise when walking.
