Both can be true.
I think both were true.
You're thinking too logically IMO.
Yes, she is that horrible. They (H&M) both are.
Most of the family were late in arriving anyway. Can you imagine having to guard every word and action in your grief? Can you imagine having an argument in-situ with some dum broad who demands to see the Queen laid out so she can take a pic or write about it later.
The only reason why MegZZ can't write about this sad event is because the entire world knows for a verifiable fact she was NOT there.
Why would she be there? QEII was not her grandmother nor her Queen (even if she did make sure she got a duchess title). MegZ knew the Queen for a couple of years max before she ran away, met her only on a handful of occasions, wasn't even a British citizen.
Doesn't mean she didn't already try to sell the Queen's last breath to the highest bidder.
