Attends a daycare center five days a week
Four years old
Recently swam in a local pond
Nausea and vomiting
It's almost like they're pieces from some peculiar medical diagnostic game. I have no idea what they're supposed to mean. One of my co-workers suggested that the envelope had been storing many of these, and the customer hadn't emptied it completely before putting the payment inside and mailing it.
So: what sort of purposes (nefarious and otherwise) can you imagine for slips of paper like these?
