I thought I was my mother’s firstborn. But in my teens, I uncovered the family secret that she had gotten pregnant as a teenager (before she met my father) and had given the baby up for adoption. She had even recycled that baby’s middle name to use as my first name.
My grandmother confirmed it was all true, but my mother lied to me about it, saying it was false and refusing to talk about it further. She was a pathological liar overall, so one could generally count on the opposite of what she said to be true.

Story 10:

My uncle’s wife’s sister got pregnant at a young age, so their mother claimed the baby as her own when he was born. He eventually found out that his sister was actually his mother, his mother was his grandmother, and his other sister was his aunt. My family is so big and full of drama, with countless scandals. It’s a mess, but I secretly love it.
Story 11:
I saw my boss at a restaurant with his wife. I went to say hi. He had told us a day ago that he was going to become a dad, so I smiled and congratulated his wife. She turned pale.
My boss grabbed my arm and whispered, “You idiot, I was talking about my girlfriend. My wife actually is incapable of getting pregnant.” He added, “You should be more careful with what you say next time.”
It was one of the most shocking situations I had been in… ever. The worst part is that he was my boss, and I had to see him every day. It made our encounters so awkward.
