The Middle School only gets ten minutes for their morning recess before they have to go to their next class. The Lower School gets a 15 minute recess and a 25 minute recess after lunch. On the one day the seventh grade gets lunch recess, it is only 10 minutes, meaning they only get 5 minutes before they have to leave for classes. Why couldn't the Lower School just wait five minutes for the Middle School to get off the turf? They have a lot longer recess than the Middle School.
