Postcard sent by John (the UK), with Jane Austen words on a letter from January 21, 1801: "Expect a most agreeable letter, for not being overburdened by subject -having nothing at all to say-there shall be no check to my genius from beginning to end."
On the back, more mail words:
"The desire to write a letter, to put down what you don't want anyone else to see but the person you are writing to, but which you do not want to be destroyed, and perhaps hope may be preserved for complete strangers to read, is ineradicable. We want to confess ourselves in writing to a few friends, and we do not always want to feel that no one but those friends will ever read what we have written." (T.S. Eliot, 1933)
