Mandarin lessons

Thomas has been taking once a week Mandarin lessons for the last few months. I was just listening to him with his teacher tonight and I had no clue what was going on!! She was pretty much just speaking to him in Mandarin and he was speaking right back. I was so amazingly impressed... an hour a week and he seems to be learning so much!!! Gary's also teaching him and Emma some basics in Mandarin such as colours, numbers, animals, body parts and all that good stuff. Emma obviously must think that Mommy is a moron because she regularly tells me that Daddy is teaching her Chinese and she's teaching Mommy! The saddest part is that she's right...her Mandarin vocabulary has way surpassed mine by now, and Thomas' even more so!
