The language of Home

Charlotte loves to type numbers and letters on our laptops. She is a very quick study. As you probably know, Charlotte attends a Mandarin language class every Monday. Today, I handed her a cup of water and she said "thank you mommy" and I said "you're welcome, can you say thank you in Mandarin?" and she replied "no, in Home." I love that she thinks of English as Home Language and Mandarin as School Language.
