This was my husband.
When he and his best friend were young, they met a person in a video game who gave them a sword. At the time they said they would name their firstborn child after this person whose name was “Kravian”.
Well the friend had four kids and never named one of them after this person. Which to my mind and validated the promise. My husband didn’t seem to think so and was determined to name our daughter “Kravian”.
I had to fight him for months and talk to the doctor. But happily we settled for Kira Stormageddon
And this is how Doctor Who saved my marriage.
