When I was a kid, the first snow of the year would always fall sometime in December in the Tokyo suburb where I lived with my parents. Looking back, it was strange how a small soul such as myself got to learn the regularities of the world. No adult ever told me when I should expect the white blessing from the sky above. In the child's psychology, I would always look up expectantly, when in the December sky some clouds gathered to darken the earth below.
With the first snow, I was psychologically "ready" to welcome the new year.
Recently, possibly due to the effects of global warning, we have less and less snow around Tokyo. It is not unusual now that no snow ever falls on ground in December, or throughout winter. Thus, my childhood's annual ritual of the heart is now moot.
Climate change affects many things. My precious memory is one.
