Every family has an "open secret" that everyone (or most everyone) knows about, but no one talks about. Maybe it's your uncle's drinking problem. Or the family history of mental health issues. Or dad's second family in Ohio. Whatever it is, you never, ever bring it up—unless you want to ruin Thanksgiving.
1.) From thedoodely:
Apparently our dad had another kid about 8 years older than me. My mom blurted something about it after their divorce when she was pissed about something. It was along the lines of "if he thinks he can forget you exist like that other kid of his...", she then turned very white and I was never able to get more out of her than that. My dad pretends he doesn't know what I'm talking about but has apparently told my brother a bit of the story and then backtracked and never talked about it again. So yeah, apparently I'm not the oldest.
