I DID NOT KNOW THIS!! DID YOU??>Mirror or two way glass????? YOU NEVER KNOW WHO'S WATCHING OR 
>WHEN!!!!!!!!!!!!!! How can you tell when you are in a room, restroom, >motel etc. with a mirror or a 2-way glass? Here's how: I thought it was >quite interesting! And I know in about 30 seconds you're going do what I >did and find the nearest mirror.... Do you know how to determine if a >mirror is 2-way or not? This is not to scare you, but to make you aware. >A policewoman, who travels all over the U.S. and gives seminars and >techniques for businesswomen, passed this on. When we visit toilets, >bathrooms, hotel rooms, changing rooms, etc., how many of you know for sure >that the seemingly ordinary mirror hanging on the wall is a real mirror, or >actually a 2-way mirror (i.e., they can see you, but you can't see them)? >There have been many cases of people installing 2-way mirrors in female >changing rooms. It is very difficult to positively identify the surface by >just looking at it. So, how do we determine with any amount of certainty >what type of mirror we are looking at? Just conduct this simple test: >Place the tip of your fingernail against the reflective surface and if >there is a GAP between your fingernail and the image of the nail, then it >is a GENUINE mirror. However, if your fingernail DIRECTLY TOUCHES the >image of your nail, then BEWARE, FOR IT IS a 2-WAY MIRROR! "No Space, >Leave the Place" So remember, every time you see a Mirror, do the >"fingernail test." It doesn't cost you anything. Remember: "No Space, >Leave the Place" Ladies: Share this with your girlfriends, sisters, >daughters, etc.
