Yep that is right. My front door did not have a peep hole and did not have any windows near it to look out of. So every time some one would ring the door bell and I wasn't expecting anyone I would say to myself "I hope they don't kill me when I open the door." I would have never thought that except that in North Richland Hills around Christmas time an old lady opened her front door and got shot. So ever since that I have been a little worried. So a sales man come and rang our door bell one evening and as I was walking to the door I did my usual thinking as posted above. The man was saleing peep holes and installing them. So I said "YES". I love it. You never realize what you like or miss having until you don't have it. So since then every time I walk into the office and past the front door I just take a peep out side. I love it!
