My third visit to Mr and Mrs Y to post some letters for them, so it's a bit of a well worn route between their flat and the local post office and back again to drop off the change. Mrs Y and I then ended up having a long chat about our respective heights, and the fact that she'd also noticed Japanese people were getting taller. I'll admit it was a slightly surreal conversation but an entertaining end to a Thursday afternoon, although as a result I will be keeping a sharp eye out for potential candidates for the Japan Olympic basketball team.
