He must be taught to take off his shoes in a mosque and to wear his hat in a synagogue and to cover his nakedness when taboo requires it, or our tribal shamans will burn him for deviationism. But, child, by the myriad deceptive aspects of Ahriman, don't brainwash him in the process. Make sure he is cynical about each part of it.
