I just spent about five minutes on the front porch in my pajamas cheerfully educating a Jehovah's witness about Judaism after he'd come to my door to proselytize. Somehow, the conversation ended with me inviting him to drop by the synagogue I attend any Saturday morning if he wants to learn more about Jewish religious texts and theology.
He was very friendly, very polite, and had his jacket on cross-buttoned. To steal a phrase from
misshepeshu, I wanted to pinch his little cheeks.
