Another seasonal / cultural quirk that Japan has - which I am beginning to appreciate in this sweltering melting potroasting heat mecca of Hong Kong -- is the Shochu Mimai note.
A card or a postcard typically depicts summer scenery - and it's a breezy heartfelt custom to inquire your family and friend's health during the abyss of summer heat and humidity.
In any case, I do love love love the occasional snail mail in my post box. Instead of the usual bills and rags. Doesn't everyone?
*Ok never mind the carbon-footprinting guilt trip on this one - if I think about the plane, the postal truck for my wee card to be delivered to the other side of the world - of course I just want to sigh sigh >>>
