What do you guys say or do when you suspect a high school student is lying about throwing up or being sick? I need help with a good response that sounds professional and caring. Our school policy is to send home for any vomiting, but if it is not witnessed, I can not prove it happened and it gets to be a he-said-she-said thing. Parents will buck if I send these (typically chronically absent) kids home. So what's a nice way to say "Sorry, kid you're going back to class, and if you vomit again make sure a staff member sees it." I have the same issue with diarrhea, these older kids report having diarrhea more than 2 times because they know that's our sick policy. I think they just don't want to be here and need a nice way to say they're staying. They put on the pitiful face, but I'm not fooled.
