Today, three beautiful teenage girls are lounging around talking about getting nits. Lily says, “My mum once counted a hundred head lice off my head in just fifteen minutes!” The other two find this outrageous and gasp, hands clapped in disgust to their lipticked mouths. “And then,” Lily continues, “she made me bend down and sit for an hour with my head in a bucket of vinegar!” And the three of them absolutely explode with laughter at the ridiculous image this conjures. They are still shedding tears ten minutes later. I am still giggling too, but more out of disbelief. That someone so very lovely and intelligent could have a parent so very ill-informed.
