Yesterday was helping YX to brush his teeth. We did this every night in order to made it a good habit. *Brush....Brush....Brush* Suddenly, YX look straight at me (I squad down so can be at the same height as him). He looked so serious and moved his head towards mine. I was thinking, oh no! is my face dirty? Then YX said " Emmm.......got YX inside" (pointing at my eye). Hahahaha.... he saw the reflection of himself. How silly.
