If I don't recognize the name or the number, I don't pick up. Ever. If its important, they'll leave a message. Only problem - our bedroom phone is a land line with no ID. I just let it ring or race into the office to see who it is.
Can't fathom how Georgie residents are dealing with the onslaught (related to your upcoming election). Here is Oregon we go very few TV ads during the presidential campaign (as we aren't a swing State).
Kinda sad that screening/ignoring calls has become a way of life.
