< does the bar stock champagne?
The idea that a letter is less a communication directed at a specific person and more about general ruminations on one's own life. Seems similar to a journal entry that is tangentially related to the intended recipient.
Yes--though at the same time, I would never strive to please in my journal, and you have to try to make your letters appealing to the recipient. Or at least I feel I have to, to be worth the post office's efforts.
