You realized that everything you had been taught was a lie??
It didn't work quite the same way with me. What happened was, it became clear that there were different categories of "true." In one basket were scientifically-provable, demonstrable facts that you could count on all the time. In a different basket went the things that were either obviously-untrue, imaginary, or otherwise unprovable, which you nevertheless had to
pretend really existed for various reasons. These included such things as religious teachings, patriotism, gratitude, school spirit, love, and emotional identification with fictional characters. I couldn't understand what purpose was served by imagining all those things were real, but other people seemed to get upset if you didn't, so it was best to play the game and avoid getting into arguments.
