I am so sorry to hear that some on this forum have been concerned about the potential for something like the behavior mentioned in the CL ad to occur in their own lives. I believe that anyone who does this type of destruction to their own or someone else's property in a fit of anger has serious anger and emotional issues. I'm not qualified to diagnose the specific ones, but the specifics don't matter.
What does matter is that this type of violence against property can easily escalate to violence against people.
If anyone on this forum or anyone you know is with someone with this type of anger/emotional issues, please get out. Call a hotline, a friend, or the police. Protect yourself. The person doing this does not have emotional maturity but he or she may be great at manipulating your emotions. Do not let this person rationalize his or her behavior or blame it on you. This type of behavior is completely unacceptable.
This book is on my reading list and comes highly recommend by a writer at the Washington Post: Gavin de Becker's The Gift of Fear and Other Survival Signals that Protect Us From Violence
Game set and match.
