Ways to Tell it is Semester Break
The line at the bookstore is only 3 people deep.
You maintain your level of checking school email, but no new mail arrives 8 out of 10 times you check.
Your desk starts to resemble something other people use.
Your computer now has folders for all the classes you took, they're sorted by semester and then by class.
The year's worth of photographs you've taken now are sorted into topics, all 32gigs worth. Or was that 64?
In any event, the things that one says need to be done finally do get accomplished when the schoolwork goes away.
