Since our mum died 2 years ago my sister and I have stopped seeing each other. It's complicated but I'd sum it up as she's a narcissist who finds fault in everyone else but never takes any responsibility herself. We communicate about our parents will and financial stuff, but that's about it. I find it very difficult and it upsets me a great deal but it's her choice.
A couple of months ago she sent my daughter - who she likes - a generous gift for her 21st. But it was my son's 18th a few days ago and nothing, not even a card. She's less keen on him, he's not as easy going as his sister and they've never bonded at all.
But just to send nothing, I'm appalled. What would you do?
