The day I thought would never come is here!
I agree with the last posts by @polkadotdalmation @MamoruHisaishi and @Sudeko
Thomas Markle should indeed focus on the 5 grandchildren he has not seen, and the Markle sibs should focus on their estranged kids.
The fact that the hated Meghan is at the centre of this has blinded many to seeing this for what it is. It is a step-family drama of the kind we read about on Mumsnet all the time.
Samantha and Tom Jnr clearly resented their younger sister because she was raised with something they did not have, not just money, but a loving father and mother. They both ran away from their mother Rosalyn to live with Thomas, after he had left them in Chicago. To this day, they are estranged from their mother. In her book, Samantha labels her "promiscuous".
It cannot have been easy for them to see their father loved up with a new child, a new wife, in better circumstances than he had with Rosalyn. And when that marriage broke up, to see Meghan grow up, not in an acrimonious divorce like they did, but in a fairly harmonious one, switching homes, still loved by both her mother and father. Meghan then became the first member of the family to get a university education.
Meanwhile, they went on to have their own dysfunctional relationships, in low paid jobs, with their own children not talking to them, while Meghan is happily married with a husband who adores her and their two children.
It can't be easy being Samantha and TJ.
If they were not so terribly bitter, I would even feel for them.
