As a child, my father would insist we go out on all those "special days" as it was "a good time to find people home"
Also, I am sure that when people would get annoyed, it would play into the persecution complex that witnesses just LOVE
He would LOVE recounting the experience of a man who on christmas day got angry with us (me a 10 year old) and snapped at us : "Go away! Imagine coming and talking about the Bible on a day like today!"
The irony was funny I will admit!
