COMMON SENSE IN THE HOUSEHOLD.
Reading edition
BY MARGARET VANDEGRIFT.
When you're writing or reading or sewing, it's right To sit, if you can, with your back to the light; And then, it is patent to every beholder, The light will fall gracefully over your shoulder.

Now here is a family, sensible, wise, Who all have the greatest regard for their eyes; They first say, "Excuse me," which also is right, And then all sit down with their backs to the light. But their neighbors, most unhygienic, can't see Why they do it, and think that they cannot agree, And always decide they've been having a fight, When they merely are turning their backs to the light.
