I guess one's perspective colors it. My thought in seeing the Instagram posts for MM's birthday is that these are truly classy people. (And a BRF fan, I am not.) HM posted a lovely and flattering photo of M with her, both smiling and seeming to be having a good time together. The Cambridges posted a lovely and touching photo of M reaching out to a small girl. Nothing but good wishes. The PH/MM pair, however, have posted awful things in the past, such as suggesting that HM doesn't own the title "royal", etc. Just nasty.
Many people, after being targeted as they were in FF, would have skipped the birthday wishes. So, my hat's off to the Queen and PW/DoCam.
Ironically, in FF, PH (or, ahem, his "friends") takes the opportunity to pass along to the entire world private comments PW made to his brother, but insists on privacy for himself and M. Don't think I'd be sending many birthday wishes the way of my brother had he done that. PW grows in my estimation every day. Classy. Very classy.
