That teacher is the radio of kindergarten. If she knows something then it will spread in whole school and I don't want that to happen.
"Yu Chen, Yi Chen if teacher Su asks you about your father just tell her he is busy with business trip ok."
"Okay mommy. She asked me once and I told her father is in business trip.",...Yu Chen
"I also told the same.",... Yi Chen
"Good!"
"Mommy do you know Teacher Su tells everyone. Once one of the girl in the class kissed me on my cheeks and Teacher Su told everyone in the school. Everyone was teasing me.",... Yi Chen
"A girl kissed you? Why didn't I know about this?"
"It was when mommy was coming late. Later we forgot.",...Yu Chen
"Ah!(laugh) so what did you do Yi Chen?"
"I told her to apologize to me because she can't touch me however she wants. Then I washed my face."
"Haha I expected that you would do that."
