I don't have any problem with "click" hang up on any caller that takes too long to respond to my hello or a voice I'm not familiar with. So much easier than dealing with people trying to sell or scam me. We've had several instances here where people called saying they were grandchildren and in dire trouble. They gave enough personal info (taken from facebook, etc.) to fool the person. The scams were caught by bank personnel and the police were notified. Our paper is good about giving us info on these scams. All this is another reason I stay off facebook, twitter etc. I'm old school and like a card or phone call.
