“My main wish is to get my books into other people’s rooms, and to keep other people’s books out of mine.”
—Samuel Butler (1835–1902)
“Is a man too strong and fierce for society, and by temper and position a bad citizen,—a morose ruffian, with a dash of the pirate in him;Mnature sends him a troop of pretty sons and daughters, who are getting along in the dame’s classes at the village school, and love and fear for them smooths his grim scowl to courtesy. Thus she contrives to intenerate the granite and the feldspar, takes the boar out and puts the lamb in, and keeps her balance true.”
—Ralph Waldo Emerson (1803–1882)
“And seniors grow tomorrow
From the juniors today,
And even swimming groups can fade,
Games mistresses turn grey.”
—Philip Larkin (1922–1986)
