Yes, Anne does a lot of engagements (she did 560 in 2012 and 454 in 2013) , but I'm pretty sure she didn't start out doing that many. I imagine it was a gradual thing.
It's strange that William is called lazy and workshy. It's like people forget that he had a full-time job for years. I just don't see how one year invalidates his many years of service.
So far this year, he's done 91 engagements (Kate 66 and Harry 55). People may think he's not doing enough, but right now his numbers are not that far off from Camilla's (who's done 141).
I'm curious to know what type of numbers people think the Cambridge's should do. Should they replicate the numbers Charles put up? Do 300 or so like Andrew and Edward, or are the 200's that Camilla and Sophie do okay?
