Okay, I don't care that this is on HN, but rather why? Yeah, yeah, "anything folks are curious about...", but as one who has spent plenty of time hanging around Anabaptists (who often wear head-coverings), umm, so? In contrast to Muslims, and "oh, did you know Christians do it, too?" Or "yeah, but which Christians?" Or just "people are weird"? :-) Anyway, as one who never gave much thought to a woman with a little piece of cloth on her head in church, just curious what others have learned today, I guess.
