Hello how may I help you? can i ask you something about the weather? Of course, what would you like to find out about? is the thunderstorm that was supposed to happen this afternoon still supposed to happen? No thunderstorms are currently predicted for your area today. are you sure about that? the forecast this morning said there was supposed to be one Forecasts may mysteriously change, due to many weather-related factors. so weathermen are basically useless then? Weathermen are not useless, they don't predict the weather but computer models do. Sometimes there may be errors. ah ok, so computers are useless then! If they were then I wouldn't have been created now would I? good point, you win
