A childhood belief about lies

I convinced my little brother that bubbles were your possible futures and once you popped them, they were destined to happen to you. I told him that the reason you see a tiny version of yourself in them (your reflection) was because that was the future you but that I could see really well and only I could make out what they were. I would blow a bunch of bubbles and say there were a bunch of different futures in them sand watch him excitedly pop the ones that I told him were really good. Sometimes when he was acting up I'd tell him one of the bunch was bad and then watch him pop and bubble and shout "oh no! Not that one!" But then after he'd freaked out about whatever bad future I said would happen, tell him the next bubble undid it. Some of his bad futures were getting bad grades in school, growing up ugly, losing all his teeth, or just getting trouble for what he might have done that day. But the future that made him really lose it and meltdown was that he would fall in love and get married. For some reason that future was utterly unbearable to a five year old.
