The fact that head lice is not an illness is of no concern to me. I am bothered by the expense and the time involved cleaning up the mess. I understand how easily its transmitted, I have 3 daughters. As a person, though, it is my duty to let others know if we've had this problem and remind parents to check their children's hair. Common courtesy. We're all human, no need to be embarrassed. It can happen to anyone.
Please, if you have children that have lice, or any other bothersome bug, let the rest of us know. Anonymously if you have to. If I hadn't received a phone call, I would never have thought to check my kids' hair. And then I would have continued to send them to school... with your child.
