Is it a just another social trend or some other kinda misguided response to happiness, excitement, surprise, dismay, fear…just about anything that requires an emotion-enhancer? Why do women – from beauty contestants (that is to say “bachelorettes”) to school girls – cover their mouths. It’s America and you probably have some sort of dental care, so it’s not your choppers. So you’ve watched the series of movies with the crazy native shirtless werewolves and horny glowing skinned tree-climbers but you’re NOT a vampire with big pointy teeth. So why the mouth cover?
