While I don't practice walking around as if the house was full of smoke, sometimes when I get home, I pretend that I came home to a break-in (example, front door ajar). In a real situation I might call the police and let them look around, but I like to proceed as though the cops are unable to assist. I basically go commando-style through my house with whatever available weapon is on-hand, taking each room and closet/space, as I go along, "securing the building", aggresively creating a path that ensures "they" can't get behind me, and eliminating all possible hiding spots.

So, you're post makes me feel like I am not totally alone...but that doesn't mean I don't "get a little crazy".

I define crazy as being mental to the point of endangering self or others.

I don't think you are crazy, unless you think you can successfully negotiate a house fire at standing height.
No, I simply think that you love your family and want to keep them as safe as possible.

LOL.

DON'T TOUCH THOSE DOOR KNOBS!!!
