Has anyone ever thrown up on themselves at your job? Unless you are an ad man from the 1960s (Mad Men, anyone?) or a doctor, probably not. One minute the 1st grade class that I am substituting for is enjoying their snack time, and the next a little boy is approaching me with vomit all over the front of his shirt. As I try to suppress my own gag reflex, he tells me that he is feeling much better. I reply that while I am glad to hear this, he still needs to go to the nurse and get a fresh shirt.
