That's why I always smile and thank them. We always go in twos when door knocking. We went down to Altus for a special election and parts of there we refused to door knock. It is a small town while here in Norman which has 100,000, I am not afraid to knock in any part of town.
Going in twos is a smart idea. At one point, I had a part time day job, and would take a couple of kids, the dog, and a heavy Mag flashlight.
