I'm convinced some people have actually been raised in a barn. There are some things you should know to never ever do and some people are so clueless, they just don't know it. Never pull a fire alarm when there's no emergency; you'll get inky and maybe even arrested. Don't touch the third rail of NYC subway trains; you will pass on to the next mortal plane. And for the love of all that is holy, don't hang a dress on indoor sprinklers instead of in a closet. It will only lead to flooding and misery. A sprinkler that exists only for emergency situations isn't just going to chill until it smells fire. It's going to spring into action if it's yanked or touched, and that is some common sense that so many people lack. The wife of a wedding makeup artist shared the story of an incompetent wedding planner hanging the brides dress on a sprinkler, and it is a devastating sight to behold.
