It all comes full circle

You know when you're playing ToeJam & Earl and the level map starts out all black and as you begin exploring the world you start uncovering portions of the map at the same time, until the entire map is visible?

I basically go for walks and start in random locations (thinking I'm really far from anywhere I've been before), only to find myself at a landmark I've already visited, but this time uncovering it from the other side. More often than not do I find myself approaching a building or walking up a street from the opposite direction that I had initially walked before. I pride myself on my EXCELLENT navigational skills so when I find out I've been to a certain location before, my whole internal compass jars back into place. Then it's all "Holy shit! So THIS is where I am!"

And then everything in Tokyo is closer than once thought. I think it's a safe assumption that most stations are only within 15 minute walks from each other. Therefore, riding the train has duped me into thinking that the stations are far from each other.
