Well, after trying every city in the US with the same name as the one I was born in, none of them ever changed the likelihood of my marriage being arranged by my parents. I also tinkered with time zones and the specific time I was born (I know it was around 2-3 am) and none of those factors made my chance of my marriage not being arranged by my parents go anywhere below 100%. Might just be something wrong with the day I was born. :/
Actually I can kinda see how this makes sense. Since my marriage can only happen if my parents arrange it and there is no chance of that ever happening it means I will likely never get married. Good to know.
