Dear Sir or Madame,
I think I speak for every mother in the world when I beg of you to please spare my child(ren) of your stomach flu germs. If your child has the stomach flu or has had it in the past week, stay home, please. I do not want these germs near my child, as it turns out, my child will inevitably ingest said germs and become violently ill usually at 3AM. AND I do not want to have this predicament on the eve of my other child's dance recital for the second year in a row. In fact, I hope I live the rest of my life and never encounter a stomach flu germ ever, again.
