Ash spoke Korean but did not hear it much in their new country. Bailey used Ash's language.
Ash just got here from Korea. She is learning a few words, but I must speak to her mostly in Korean. It's good that she has you to help her understand what is being said. How do think I can help her learn English faster? Why don't you speak to her in Korean and then repeat it in English. That's a good idea, that is how I learned.
