Jane comes from Mexico. She is a good student. She likes to keep notes of the new words and expressions she learns in English.     She usually writes them in a notebook.
One day, she asked her teacher about them. “ 
There are some expressions I don’t understand.”
“Sure. What questions do you have?”
“She’s blue today. What’s the matter? You’re yellow? A little white lie (谎言). White lie? She has a green thumb (拇指).     ”
After looking at the notebook, the teacher says, “In English, Jane, blue sometimes means sad. For example, she is blue today; it does not mean that she is wearing a blue coat.   Yellow means afraid. She has a green thumb. It means that she is good at growing plants. And a white lie is not a bad lie.”
“ ”
“For example, I give you some cake. You don’t like the cake, but you don’t say that. Instead, you say, ‘No, thanks. I’m not hungry!’ That is a white lie.”
“I see. Thanks a lot.”
