but i never ever sit with my back to the door when i am at the VA.
if i have to go see the head shrinker...i sit and move the chair to block the door so he/she has to leap from a window to get out if i make em nervous

i use this in the world as well, I always have an exit, even when we drive into our driveway.....
search as the headlights flash the yard, usually see lots of deer.
take a quick look at the doors.
we are lucky, as we have only tow houses on my street. mine and my parents next door. but lots of dark areas if a bg wanted to hang out.
so far we have only be startled by deer looking for something in my bbq
i like the hats and tats thinking, might add baggy pants to.
