There are two angels, that attend unseen
Each one of us, and in great books record
Our good and evil deeds. He who writes down
The good ones, after every action closes
His volume, and ascends with it to God.
The other keeps his dreadful day-book open
Till sunset, that we may repent; which doing,
The record of the action fades away,
And leaves a line of white across the page.
—Henry Wadsworth Longfellow
