Random Thought Of The Day

What is the purpose of thunder and lightning? Besides annoying the shit out of us? It's like snow, it serves no purpose whatsoever. Snow just sits there, it does nothing for the environment, its annoying to drive in, it gets all dirty and gross after about a whole 2 days. So wtf? I cant stand when people say "Oh but its soooo pretty!", no its not. It's fucking annoying. And same goes for thunderstorms. I know rain has a purpose so why the hell does it need its wingmen Thunder and Lightning? I guess I dont like any sort of precipitation... Ok I'm done now.
