i never thought about language. My oldest has taken Spanish, french and now Chinese. Shes not fluent in any of them but can understand most of whats spoken to her. She thinks it funny to teach him phrases that I don't understand. He was running around saying "drink up" in Chinese for like a week and I couldn't figure it out. She said she was preparing him for his college years lol oh and he will NOT tell me what hes saying even though he knows because his sister tells him.
