"But I wonder how you would feel, is it more insulting that people respond to feeling disregard and feeling ignored or is it best that everyone continue saying nothing?" she responded.

The length of her stay in the United Kingdom is unknown, but it is thought that she intends to confront Meghan, 36, over their father's ill-health.
The 74-year-old did not attend his daughter's wedding after reportedly suffering a heart attack in the lead up to the big day.
Sources have revealed to the Daily Mail, however, that Meghan would never entertain the idea of a showdown with her half sister.
"And you know, I think everybody was hurt not being included or invited to the wedding", she shared with host Jeremy Vine.
Earlier this month, Samantha went on a furious social media tirade about her sister and her new husband. "I would say she's found her prince".
Just this morning, Samantha took to Twitter to slam "journalists" and "tabloids" who she believes have painted her father in a bad light. But I think, quite frankly, she probably believed what she was seeing as well. "The duchASS can bow to the daddy".
The source added that Duchess Meghan has other things to concern herself with, such as finding her mother, Doria Ragland, a place to stay when she comes to the United Kingdom for extended visits.
She wrote: '[He] thinks he can shoot someone and still get votes.
"Harry doesn't mind Meghan's mum staying with them for a couple of weeks until she finds a place of her own, but only as a short-term solution", a palace insider told Life & Style.
The sisters last spoke three years ago, before Meghan's relationship with Prince Harry, but she has given countless interviews about Meghan since her engagement was announced.
In the beginning of the interview, Vine pointed out that Samantha had visited Buckingham Palace hoping to see her sister, but expressed that Meghan understandably wouldn't want to see her after recent events.
'And as far as her dad's health is concerned, Meghan is not anxious.
"She knows exactly what's she doing, she's very strong and she's a great speaker".
