>>1234320Acquired as a need for survival since grandma who raised me was absolute dogshit at directions. So by the time I was 4 I had memorized all the lines, services and trains that ran on all the lines in the Tokyo area and the bus services that run between Matsudo, Kameari and Soka station since thats how I had to get home. Thats how it started I still have most of that shit memorized granted Japanese people find it funny I refer to the Urban Park and Skytree line as the Isesaki and Noda lines like they should be called.
