This code is very simple and very direct. You are sulking. Stop sulking.
A genuine sulk is an exaggerated posture to show that someone is upset and wants others to know all about it. This 'upset' is to be used as a sort of lever to get what is wanted.

On the basis that parents may not like to see their loved ones upset, the sulk has a purpose. The more successful sulks are in achieving their objective, the more frequently they may be used. The code makes clear to everyone that 'the sulking game is being used'.

It is not always easy to distinguish between a sulk and a genuine hurt or disappointment. The outward symptoms of withdrawal and quietness may be the same. The difference is that one is a reaction which cannot be helped (hurt) and the other is a deliberate act with a purpose (sulk).

People who have developed the fine art of sulking may really find it difficult to get out of the habit The code may help by increasing insight and by suggesting it is silly.
