Sometimes I write my mother a letter, attempting a lyrical prose style, (although I often fail at it, due to rushing to send it and not double checking what I wrote), but after I send it, she complains that I'm not using the right style for a personal letter.
So my question is, if I want to write a personal letter to someone, as long as the letter is of a kind nature, does it matter what style I write it in, as long as it uses modern English, and as long as the recipient can understand it? Another question I have, which is related is: Have any writers in the past two centuries written personal letters in a lyrical prose style?
