Dreaming in French

A boy was having a lot of difficulty in French class.

To encourage him, his teacher said, "You will know you are really beginning to get it when you start dreaming in French."

The boy ran into class all excited one day, saying, "Teacher, teacher! I had a dream last night and everyone was talking in French!"

"Great!" said the teacher; "what were they saying?"

"I do not know," the boy replied; "I could not understand them."
