At the main cathedral in the Plaza de la Catedral, there are signs in English and Spanish advising that men must wear long trousers, and womens' blouses should have sleeves. Since I never wore long trou while off duty, I never got inside the Catedral.
I’ve heard it rumored that the Sign of Peace is going bye-bye. It’s optional right now. I have been to Mass when the priest does not do it. Keep your mind on Jesus!!!!
