我的牙白不白

Keke is very reculatant to brush her teeth. She actually is chewing her brush instead. I was downstairs watching TV, Keke shouted at me upstairs, “ 我的牙白不白， ”, I found her reached out her head from upstairs and showed me her teeth. It was really far away, but I told her, "真白". Sometimes, Keke is running down and grinned at me, “ 咧着嘴 ” shows her teeth to me then rans back.
