【美国小孩学英语】5 眼泪 (2/3)

李瑞波:if u begin to cry ,there are many more tears,the holes cannot drain all of them , then,extra tears spill out onto u face.

李瑞波:if u look into the mirror, u can see tiny-holes in the corner of u eyes, each hole leads to a small tube that runs to ur nose.tears run slowly into this tube drip by drip.day and night the holes drain tears away, if they didn't, u would always look as if u were crying.
