The last time I traveled the world, I couldn't leave for a long time because the portals were too flat. I had to wait until they got fatter.
And now I'm here. The thing is why I take all these trips: I really want to send a message to my next self, the next Dagie.
I fold the time, I press the spiral down one dimension less, from four to three, then two suddenly collapse and see each other! I don't know if that works and ... oh, now I'm in the supermarket, that's good, because I actually need some tube soup, frozen.
