Good news from a far away country

On a visit to the Hong Kong General Post Office, I saw the former gate kept hanging on an inner wall, of the today very practical building. It says: "As cold waters to a thirsty soul, so is good news from a far away country". I know this spot, as I always liked writing letters and postcards, and came here often during the days living here. It is an unpractical, but beautiful alternative to the electronic means we have. Imagine, back in these days, what it meant to receive somewhere in England a letter from the Colony "Victoria", Hong Kong. Perhaps generations later, these papers were found in an abandoned storage in a shoe box. And what stories they told, and what travel they witnessed? And what do they tell the people who find them? Wondering who will log on our servers, and download our emails one day, long after we have gone. And how would we they even find the plot of our life's stories in all these gigabytes? Will they have to do "Data Mining", or find love letters by "Big Data"?
