Answer:
Culture shock
Explanation:
In sociology, the term culture shock refers to the feeling of confusion or anxiety that one person experiences when he/she travels or lives in a society that is different from the one he/she comes from. This happens because the norms in different societies can be really different from the one we belong to and therefore, the person doesn't know how to act in the new culture.
In this example, Angelica visits Thailand, when she wears shorts and tank-tops she is hostility from the locals, therefore she feels like she no longer knows how to behave or interact with people from Thailand. We can see that the norms in Thailand and pretty different from the one Angelica knows and therefore she feels confused about how to act there. Thus she is experiencing Culture shock.
