The Zeng story by Enas:

A student of the zeng culture went to the teacher and he started to talk about his problem while the teacher was fullfiling a cup with tea. The teacher was listening to the problems that the boy had been suffering before getting there. The cup of tea was getting full and the boy kept talking about his problem without stopping in anymoment. When the cup of tea started to overflowing the boy stopped talking and said to the teacher " Stop fullfilling the cup, its overflowing" so the teacher finally could talk and said to he boy " You couldn't learn anything until you are empty on yourself, you are like this cup of tea".

I think this is a good example to people who want to be helped but they don´t really listen to he people that are trying to help them. they are just talking about their problems and don´t realize the only person is talking are him.So I agree the form that the teacher uses in this case because he will realize about his own problems and will stop talking the next time to listen what is going to say the teacher.
