Outside the family, again there is no special respect for people who are only slightly older. If two people meet , and one is forty-two and the other is forrty-seven,they will consider themselves to be about the same age , and the younger will have no special respect for the older.
In fact, they probably won't know who is older; remember from Chapter Two that people from English-speaking countries won't ask each other personal questions like "How old are you?" In general, foreigners only show special respect for people who are much older: twenty or thirty years older,that is.
