Walked into work yesterday and my boss tells me that

A) my co-teacher has sprained her ankle so I will be alone for a good chunk of the day with wild and crazy kids
B) Instead of having a (relaxing) planning hour as I usually do, I need to bleach and sanitize every single thing in my classroom because
C) a child was sent home Friday with scabies

Now that's what I call a Monday back at work!
(SCABIES!!!??? God help me.)
