Born With a Rare Condition
I was there when the truth came out about my friend not being the real grandfather to his granddaughter, on her wedding day. He got a vasectomy after they had three kids, and shortly after his wife became pregnant. He knew it wasn’t his, but he made a decision to raise the son as his own.
He ended up passing away. No one found out until the bride discovered a key piece of information about herself—she was born with a rare hereditary disease.
After asking many many questions, it was confirmed that the disease came from her biological grandfather. Someone got really intoxicated at the rehearsal dinner and decided it was a good idea to tell her father, the illegitimate son, the truth. It wasn’t. Story credit: Reddit / Dinosaur
