Elastic is a very flexible material and it can be shaped in many ways. Because of its properties it is often compared to people with good nerves. And like people, elastic has a breaking point, too.Teacher is a person who shows you how a thing works or gives you advice. He has to have the nerves for explaining things to someone who does not understand fast. Therefore teachers have to be persistent. Unfortunately, it is not always like that. When a pupil gets a bad mark, he can blackmail the teacher for a better one and even say bad words to the teacher. In a situation like this a teacher can easily loose his nerves and start yelling or even hit the pupil. That is the point where they "go ping". It does not often come to this point because a lot of teachers have nerves made of steel and can control themselves.
Another situation that can make teachers extremely angry is when pupils are very lazy and do not want to work. Therefore the teacher wants to motivate them and bring them to start working. In most cases without any results. Then again he could loose his nerves because he feels ignored. This can lead to unpleasant situations.
In the end, teachers are only humans and there always has to be a cause from the "outside" to make the teachers "go ping". Usually these forces are pupils.
