Judi, You did the right thing. DO Not open the door for individuals that you do not know. Sometimes we open the door without thinking. I know I do but I'm 6' and 250lbs and usually am imtimidating to anyone who dares to ring my bell. I know how I am, if he would have knocked hard on my door we would have met face to face. These cowards are obviously watching to see where the easy picking are. We all need to be aware and alert to the folks that are roaming about. Please share your description of this person.
