We must realize the yawning pitfall in that very characteristic of home life which is so often glibly paraded as its principle attraction: "It is there that we appear as we really are: it is there that we can fling aside the disguises and be ourselves." ... It will never be lawful simply to "be ourselves" until "ourselves" have become [children] of God ... This does not mean, of course, that there is no difference between home life and general society. It does mean that home life has its own rule of courtesy -- a code more intimate, more subtle, more sensitive, and, therefore, in some ways more difficult, than that of the outer world.
- C.S. Lewis, from his essay "The Sermon and the Lunch"
