My classmate from Germany is the only foreign student in our school.I heard a loud noise coming from the classroom down the hall.It's against the rules to make noise during a test.I happened to run into my old classmate from elementary school at the store.I made a mistake on my homework and got a low mark.We have to follow the rules in order to maintain order in the classroom.I can't concentrate with all the noise my classmates are making.It is important to respect each other's cultures, especially when dealing with foreign classmates.If you break the rules, there will be consequences.My classmate accidentally marked on my paper instead of theirs, it was an honest mistake.
