22. THE list
The couple was very very religious/conservative. They apparently had a list of things they decided they weren’t going to do before marriage to make sure they stayed “pure”. I don’t remember the whole list, but it boiled down to basically no physical contact besides hand holding and not being alone in settings they may get tempted. As part of the ceremony, they read the entire list out loud and then burned it.
They then got pregnant on the honeymoon.
