While it would be desirable for Doria (and Tom) to have a nice relationship with Charles and the rest of his family...it really isnt' necessary IMO since the parties involved lived in two separate countries. It's not like Kate's parents who live in the UK, babysit when William and Kate are on tour, etc.
Most likely Doria will come over for some holidays, potential births and christenings. I am confident that Doria and Charles will have a nice relationship and comfortable relationship so that when she visits if and when Charles is available, things will be friendly.
I don't see that happening for Thomas Sr., and this was before he decided to sell his soul to the media.
In regards to the media finding out stuff about the Markles...that's another aspect that I don't understand. Somehow, someone has got their hands on the notes regarding the relationship with Samantha and her daughter Noelle, and it doesn't look pretty on Sam's side. These aren't rumors but stated facts. How are you going on preaching about a lack of a relationship between Meghan and her father, when she (Sam) doesn't have a relationship with any of her kids.
Basically, the potential for the British media to dig up and publish embarrassing details of their lives should be a concern.
I am really surprised the British media hasn't turned on her fully and started to report this. I mean, again...let's do a recap. Thomas, Sr., Samantha and Thomas Jr., desire a relationship with Meghan BUT
Thomas Sr. - doesn't speak with Thomas, Jr. or any of his grandchildren. I don't believe he speaks with Samantha's kids and the Dooley children didn't seem too concerned when he had his heart attack.
Thomas jr. doesn't speak with Thomas Jr., Samantha or his children (two sons).
Samantha doesn't speak with Thomas Jr., her mother Roslyn, or any of her children (she has three).
AND YET THEY ALL TALK AT GREAT LENGTH ABOUT THE LACK OF RELATIONSHIP THEY HAVE MEGHAN.
I wonder if they put that much effort in trying to repair the relationships listed above?
