My mum would say this to me as a child… ie annoyed that I apparently came between her and my dad by being annoying or tantrums or whatever else. I didn’t have a particularly close bond with my dad, it was probably a closer bond with my mum actually.
there was a lot of weird stuff she said and did … another that she could never choose between me or dad. Stuff you’d just not admit to a child.
is this odd or just a silly comment I shouldn’t be remembering all these years later ..
