If I ever admitted to the world my IF exists, some would doubt my sanity. Others would have their opinions confirmed. "I can't remember a time," my IF continued, "when you've had enough in your pocket to talk about being rich." I looked around, saw no one in earshot, and broke my rule against replying to my IF. "There are ways of being rich without having much cash," I explained. "You can have friends, enjoy...
