My maternal grandmother was an elementary school teacher back in the 1920s or so. Back then it was SOP for female teachers to be fired if they got married. So when grandma and grandpa got married, she didn't tell anyone at her school. To the extent any of her coworkers knew about grandpa, they thought the two of them were just dating. When grandpa graduated medical school, they had the principal of granda's school over for dinner to celebrate. "I'd like to introduce you to my husband." She quit her job on the spot, and the two of them left the state.
