I look at my call display. If it names any places that I know I do not have family in, anywhere in the world (because I do have family in places such as Dubai and Thailand)and/or if it is a 1-800 number calling, I then tip the receiver to stop the ringing. I never speak to anyone. I've found that the Shriners have learned that if they call and ask for my husband, I will ask who is calling. They used to tell me and I would tell them to remove our name from the list. Being a charitable organization, they do not have to do that by law. Now when I ask who's calling - they hang up on me. So - I told my husband that if he answers the phone in error to someone he doesn't know, ask who's calling. If it's the Shriners, tell them "he's not here". My husband is a grab the phone, it's ringing kind of person. I always check.
