The Mystery of the Mop Story

Story title: The Mystery of the Mop

Everyone at the State University knew that Donner Hall had the best parties. All night dancing and beer guzzling attracted the largest weekend crowds by far especially on the notorious second floor. By midnight every Friday and Saturday, the entire second floor was three inches deep in smashed beer cans, empty wine bottles, and stale potato chips.
   But by about 7:00 a.m. the next morning, all of the garbage was removed. The second floor residents assumed the conscientious school janitors came bright and early. before anyone woke up, to sweep up the mess.
