Your silverware jab got me to thinking of the Clintons and how it may be something of a snub to them as well if they’re not invited. I’d think they would have had more interaction with William over the years, likely including when Chelsea was over there.
The Clinton’s did not invite William and Kate to Chelsea’s wedding so it would be no big deal.....plus they are not the President at this time. Plus Chelsea did not invite the Obama’s to her wedding either. The Obama’s sure are getting dissed by everyone.
