I clicked through thinking your version of the headline was metaphorical. Nope.
• The burden of missing school days due to nits far outweighs the minimal risk of transmission, especially when the lice have been treated.
When I was in high school my grades were generally fine but I missed a lot of days due to chronic migraines. Near the end of one fall semester, two of my teachers who were real sticklers for Written Rules informed my parents that if I ended up with more than 15 days of absences, they would be obliged to fail me, even if my grade was an A or a B.
With only one absence to spare, I caught the flu from a relative who'd been traveling. Since this flu didn't really compare to my migraines I had to go to school with it. It spread. My friends called it "Wertheimer's Death Flu." I caused more than fifteen absences.
Only reason I finished highschool is one teacher spoke to all my others because he knew I was falling asleep in class or just not showing up because I was working full time and doing community service to stay out of jail. In a just society children don't work to put food on the table, they may or may not get community service as a reform attempt, but not while working and being in school, during the summer holiday or something for heaven's sake. He was so proud when I showed him my SAT/ACT results. Glad he never found out I got kicked out of my first college for being an insurance risk and never did anything with the second go around. Don't major in English or History folks.
Anyway, we do not live in a just society, so thank fuck for people who chose to simply ignore the rules.
