Sevens wreak havoc in the environment and their relationships because they are completely out of control and extremely unstable, both in their behavior and in their moods. They are as erratic as the path of a tornado, and just as unpredictable

Their mood may swing from belligerent hostility to tearful remorse to a feeling of elation, all in the space of a few minutes

Now, in a fit of hysterical passion or a moment of temporary insanity, they may well kill or severely injure the very persons they turn to. Even if they are not homicidal, deteriorated Sevens may become violently abusive to their children or spouses. If they succeed in killing or injuring others, their manic defense may finally give way to severe depression, with suicide the ultimate result

Many professional comedians are Sevens; the source of much of their comedy is the insecurity and anxiety which underlies their feelings about life.
