People need to be aware that you do not pick up the phone and dial 911 unless you mean it.  Be aware that if you are having a fuss with your spouse or significant other and you pick up the phone and dial 911, then hang up, without speaking to anyone, the police are still going to be at your door in minutes.  The law enforcement dispatcher locates the address of any 911 call and dispatches the law to that address whether or not he or she speaks to anyone calling in.  Hence, if you’re fussing and one of you calls 911, be ready for one of you to be hauled off to jail!  Don’t call 911 if you’re not serious.
