How the sisters have to wear a veil when teaching in the presence of a brother even if she's thirty years his senior. Yet, if the sisters are simply in the hall they don't have to wear the head covering like the apostle Paul commanded and they can comment even though Paul said that a woman should not be allowed to speak in church.
I remember being in high school when, during lunch break, I walked into a library room where a sister was conducting a study. Upon seeing me she stated that she had to wear a covering. Having no such thing she improvised by pulling her sweater up to her head. Cute.
