Can we all get together again Lee without arguing?

My oldest sister who is very old indeed now at 71 LOL!
She has never liked us falling out so always puts up with the bickering and tries to keep the piece, her hubby who used
to be a right tearaway has stuck by her for donkeys years now and has come to realise she will never change has agreed to us all meeting at her place.
My estranged younger brother has agreed as have others but I know it will kick off I've decided what to do.
I'm gonna buy my sisters a big bunch of flowers each and leave them on her doorstep and leave a note saying have a nice day but I'm otherwise engaged today.
I'll refuse to answer the phone then for a few days TRUE!
That's what I've decided to do so no going back or we will only end up repeating what's gone before.
When someone is the cause of family break ups but does it time and time again you just have to break off all communication.
I loved him as a kid but cant stand him now
