Admitted they would smack their 2.5 year old child if their child ever hit them.
I'm not sure if I'm projecting my own issues from my childhood as my mother was very shouty and smacked me constantly. But the idea of smacking children turns my stomach and has had lasting damage on me. Unfortunately it's not illegal so they aren't doing anything against the law but I can't stop thinking about it and have lost all respect for my friend.
Wondering if I'm BU here to feel so strongly and let it effectively ruin our friendship.
