At a friend's housewarming, you meet a young engaged couple from india. they tell you that their relationship was arranged when they both very young (she was 12, he was 14). they seem happy with this arrangement, but you're taken aback. the couple's comfort with the arrangement, as well as your initial discomfort, are examples of

This term is used to describe the process in which people learn the values, norms, and beliefs of a particular society/culture.

And you, well, you were taught differently; probably:  that is better to wait until you grow old enough, and are sufficiently independent, to support a household. So, you get a "cultural shock" by hearing about how this couple got married.
