It's the last week of school. Different grade levels have different assemblies and activities at different times to make it easier for us to manage the crowds but making the kids confused and even more hyper, as they're under the impression that no one is going to make them work this week. Also the kids may no longer use their lockers, so many of them will use this as an excuse to come to class with no materials whatsoever.
Therefore, the copy machine will break down today and refuse to work for the entire week.
It's a given.
