Conversing in chinese

Just came back from theory class at IMH. Samantha wants to buy the LCM exam book just because it has a nice cover. As usual, theory class ended 10 minutes earlier. Wow, the twins today spoke mandarin. Samantha and I were like..."what did you just say????" Shocking. Then I wanted to ask, "since when you can speak Chinese???" but instead I asked, "since when you are Chinese???" Hahaha, they were like *hmf*! Ok, that's all for now. Going for a walk. I'm in need for a sport to do this month...swimming or badminton or whatever. Ciao.
