A human being's view of himself or herself is shaped by the culture in which he or she lives

Cartoon

The dad doesn't see himself as rude because in his culture he views as licking his plate normal. He is accustomed to doing what he wants but his wife tells him about other cultures. If the husband were to stop licking his plate it would be a different culture like the ones who consider it rude to lick your plate. It is about how you shape your culture and what you are accustomed to. The dad doesn't see himself as rude because of his culture. This ties into society because someone could be doing something and not have a self image of themselves as "rude" but it can appear rude to another culture simply because their culture is shaped differently.
