So my mom told me this story, (for context me and my brothers are adopted. I have 4 half brothers and im the only white one, my brothers are black. My mom was our babysitter before she adopted us and was a close(ish) family friend) -------------------------------------------------------------------------------------When I was born my (adopted) sister was just staring at me in shock. My grandma leaned over to my (adopted) mom and just said, "Well, doesn't it take a few days for them to darken up?" No. No it does not... Anyway, that's the story of how my biological mother was caught cheating. I am living proof. There's a bit of a joke with my brothers, cuz nobody thinks we're siblings.
Maybe a story for another time, growing up with 16 siblings.
