In this chapter we use Propriety, in the sense of 'appropriate-ness' or 'acting properly' as an extension of Courtesy. That is, showing respect for an occasion or venue, and being courteous enough to behave in a manner consistent with the expectations of the hosts/sponsors and other guests or attendees.
As we find with many of the other virtues, Humility is necessary to realize that your individual attitudes are not the most important consideration in a given situation.
