Stupid, this is when a rule becomes ridiculous and self fulfilling. I have seen sisters put a tea towel on their head to say a prayer because a young brother was in attendance at a mid week meeting for field service. Does God really think that it is more respectful to say a prayer with a cleaning cloth, hanky or random piece cloth on your head?
I used to find this the most annoying rule even more annoying than the stand up or sit down for the National anthem.
