This is what I love about Japan.
I'm sitting in the park, eating my lunch, eating away at the silence with my keyboard clacking, and a steam train rolls by.
A steam train.
I hadn't even realised that there were tracks concealed beside me through the trees, but there it goes puffing, and tooting away anyway. Odd. I will investigate. Priorities though, finish lunch, then investigate. I shall uncover the mystery.
