I find letters to be such a beautiful and thought-provoking means of expression that if someone writes them to you, they must hold you in high esteem, or at the very least, you were in their thoughts long enough to speak of you with care.
It would be interesting to be both the one who writes the letter and the one who receives it, as strangers, it seems to me a peculiar plot but it is even an experiment that would be great to test, thanks for the recommendation!
