I am... a man of letters (postal not intellectual)

 Letters are among the most significant memorial a person can leave behind them.

Johann Wolfgang von Goethe

Politeness is as much concerned in answering letters within a reasonable time, as it is in returning a bow, immediately.

Lord Chesterfield

In an age like ours, which is not given to letter-writing, we forget what an important part it used to play in people's lives.

Anatole Broyard
