shocking

guys i just found out something super messed up so one of my friends is dating this guy but turns out her mum and his dad have acually slept together and they have a kid! hes older than them but still they both share a half brother isnt that kind of gross? they only just found out and turns out her dad didnt want the baby he actaully wanted her to get rid of it completely but she said no she just gave it up for adoption when he was born. parents are seriously the worst imagine if that happened to u no thanks
