I am irritated by my own writing. I am like a violinist whose ear is true, but whose fingers refuse to reproduce precisely the sound he hears within.

Each day tears away a few more leaves; and then there are the storms that break off several branches at one go. And while nature’s greenery grows back again in the spring, that of the heart never grows back.
