Before the ending of the day
Each school day ends with a prayer of Bl John Henry Newman. Most of the kids know it by heart, but I still need a little help:
May He support us all the day long, till the shades lengthen, and the evening comes, and the busy world is hushed, and the fever of life is over, and our work is done! Then in His mercy may He give us safe lodging, and a holy rest, and peace at the last!
Sermon 20 (1834)
