Hi,my name's John.It's my first day at school.
Hi,John.I'm Alice.This is a great school,but there are a lot of rules.
Really?What are some of the rules?
Well,don't be late for class.This is very important.
OK,so we must be on time.Can we bring music players to school?

Oh,and we also have to be quiet in the library.
