Thank you all for replying so quickly.
I've tried to call, but obviously didn't get through, so sent a reply saying I'd tried to call to discuss and please ring back tomorrow before 11am or after 4pm, signed it 'Love, Mum'.
There are so many items that I think a courier will be needed. I don't mind boxing things up, but I think she should pay for the courier. She has also, I suspect deliberately, not asked me to send the children's presents or thanked me for the ones I sent through Amazon direct to Ireland.
I just find it so hurtful and disrespectful to simply instruct me to send these things, with no offer to even pay postage costs, after they cancelled my trip at the last minute.
And even more hurtful that she has now almost certainly accepted in her mind that I was responsible for the estrangement and the pain it caused everyone, including her Dad. I am just the evil, bitter old woman who tries to make her feel guilty.
