Family inheritance plays an important role in determining one’s language use.
Family determines a person’s mother tongue and often the most confident language. In our case, family determines whether the second generation’s mother tongue as Cantonese or Thai, and whether they grow up as bilingual. Family can also affect a person’s language attitude. For example, the brother of the 3rd family uses the Thai language only when he would like to make fun. Therefore, for him, there’s a kind of association that the Thai language is not really for communication but only for making fun.
