Was laying in bed last night almost asleep watching Terminator 2 on AMC, when about 0030 my 15 year old daughter and her friend who spent the night came into my upstairs bedroom in a panic they were downstairs and said someone was knocking very hard on side kitchen door. told them to stay put grabbed my 1911 headed downstairs to kitchen my 18 year old daughter still alseep in her downstairs room . kicked on all flood lights 360 around house and was thinking who comes pounding on a door after midnight, unless its neighbor with an emergency . Swept the perimeter and no one to be found if it had been a neighbor surley they'd still be there? well needless to say not a good night sleep would wake up check gun and flashlight look out upstairs window sweeping streets nothing.Very strange indeed.
