It is 12:14am on Sunday in Cambridge, Massachusetts, USA. About 30 hours ago it was 7am on Saturday in Kyoto, Japan, so after two buses, two trains, two planes and too many benches to count B and I are well into Sunday afternoon. Time-travel is possible, but you end up far too tired to think of any clever way to exploit it. We're going to sleep now, and tomorrow it will finally be today again.
