We are judging these people by what is said or not said, Megan’s mother is praised for her dignity because she hasn’t given an interview , she may be a very nice woman, she may have said to her daughter ‘go for it girl, get that ring on your finger ‘. Much is said about how lonely she seemed at the wedding, why was there no member of her blood family invited.
The father is reported to be a recluse, he was once a successful man, does he have mental health problems. The sister has M.S. has this affected her thinking.
The Americans are not like the British , no use expecting them to be.
