Think about this there could be another person in your house. With modern technology you could have some one watching you with tiny cameras now your
day to day patterns. Set a system to worn him/her if you were close to them and know the perfect places to hide in your house places that you donít
even know about. Maybe in an attic.
Or maybe some thing that can hide in shadow. I mean if your some kind of commando sniper you probably know how to hide in shadows that most people
wouldnít think you couldnít hide in. Know imagine if there was some thing that had being learning this type of thing for thousands of years. Some
thing that knew human visual capability better then we did. That could just hide in the corner of vision and that the closest look ever got of it. And
if we do get a better look they kill that person (think of all the Mysteries disappearances and killings and the ones that cops have put the blame on
innocent people just to close the case ìlike the rule that you should look to the immediate familyî).
