I found this article on a google search I did about siblings copying. www.dailymail.co.uk/sciencetech/article-8661953/We-copy-brothers-sisters-adults.html
The reason I searched is that someone commented on the fact that I have 2 ES and I realised that one had copied the other in every detail from uni (I can't list the things they did because of privacy, but they made exactly the same life choices) to blaming parents for everything and trying to exploit and bully us, then estranging when they didn't get their way. Looking back, the resemblance is scary! They both seem to be influenced by their abusive father who they spent their formative years with, and don't take after my side of the family in personality. I hope and pray my youngest does not copy either of them.
My parents have always commented on how my siblings copy each other in everything- but I have never felt like I copy either of them. It's weird and probably doesn't apply to everyone. Do you have siblings that copy? Have you copied? Do your kids copy each other?
