Actually, made this decision after my mother's funeral last year, but have just made it formal.
We don't like each other, we have never liked each other, our children don't like each other.
If we had met, not being related we would never have gone out of our way to meet again.
I have forced myself to be polite for 30 years. She hasn't even bothered to do that. Once our second parent had died, I left the funeral thinking at least I never have to see my sister again, and felt quite light hearted and unburdened at the thought.
It's no big deal to me or to her.
However, a kind and much loved aunty who we see regularly rang up all happy and excited because she has arranged for my sister and her children to come and stay at the same time that I am going to stay with my children next week. She said she wanted to help her sister's children stay in touch and the cousins grow up knowing each other.
I said no thanks, I hope you don't mind, but I don't want to see my sister, so we will give it a miss.
I think she was quite upset.
