Man 20. Virgin. Impressionable. Just starting his drinking/dating journey.
38 year old woman. 5 children with 4 different Dads (one in prison). Offers it on a plate.
Mother is neighbours and friends with 38yo woman, says they are both adults and can do what they want to.
Man 20 is my nephew.
YABU - Leave him alone. He's an adult. Nothing wrong with it.
YANBU - It's all types of wrong and you are completely within your rights to be disgusted with the woman and SIL.
So bloody furious at the moment!!
