All in the Family
I think we can all agree there’s nothing worse than going out on a date with a stranger and finding out you’re related. I guess the only bright side is that they found out the truth at the beginning of the date before anything had a chance to go too far. This story could’ve had a very different ending.
It seems strange that third cousins who are about the same age wouldn’t know one another. It also sounds like they live in the same city. Is it really possible they’ve never met each other before? It sounds like they must have met at a family event. Either way, they were able to avoid a potential disaster.
