It is impossible to exaggerate the importance of performing these small ceremonies regularly, and being as nearly accurate as possible with regard to the times. You must not mind stopping in the middle of a crowded thoroughfare—lorries or no lorries—and saying the Adorations; and you must not mind snubbing your guest—or your host—if he or she should prove ignorant of his or her share of the dialogue. It is perhaps because these matters are so petty and trivial in appearance that they afford so excellent a training. They teach you concentration, mindfulness, moral and social courage, and a host of other virtues.
