In the back of my mind, the sense is hatching that what one considers traditional is heavily influenced by what one grew up seeing or experiencing; this may or may not actually be fully traditional, but has the feeling of normality and familiarity. Alternatively, this might apply to the time and situation of one's initiation into a custom or tradition in a similar way.

In other words, that's the way it was done when I grew up, so it feels right. Then someone comes along and says "No! it is done the way I grew up seeing it done!"

Just a thought.
