I recall two poet-friends:
One a public high school teacher, quite prolific as both excellent poet and gallery-exhibited photographer, did most of his work during the busy school year rather than the summer; he could never quite figure out why the pattern was exactly opposite of what people would expect.
The other, having all the time in the world to write, could produce only disconnected flashes – nothing sustained or full but wild all the same.
They were buddies.
