This is actually chronicled in a story I drew as a 5 year old...
I thought when a girl turned 20 she automatically got married to a random guy, and getting married caused her to automatically get pregnant. In my picture book I drew them falling in love, then walking out of the church with her hand on a bulging belly. Wow, I was messed up.
