I hope they catch that guy — he has moved my keys, too! (And glasses, though he sometimes mischievously puts those back on top of my head.)
In addition to questioning why every sentence out of your mouth seems to start with, "Now where'd I put my…" you may question whether, when there's actual trouble, you should call 911 or not.
Laws say that you are only to call 911 in an emergency situation where the safety of people and property is at risk, like in the case of a fire, a crime in action, or a medical crisis. It's not an emergency if the situation isn't dangerous and immediate action is not necessary.
You should not call 911 if there's a car accident but no injuries; to follow up on an auto theft report; or if there had been a crime but the perpetrator — and maybe your sanity — has left the premises.
