and partying abroad ...alone ?
Shades of his Danish cousin and counterpart there...(last year at the Burning Man)
They're not joined at the hip as far as I'm concerned.
But the difference is that Derf is likely cheating (we're well aware of his predilection for pretty blondes) and has for years, Haakon has kept whatever indiscretions discreet. In either case, while I generally don't sanction or encourage cheating, I wouldn't blame either one of them.
The press is pretty easy on the Scandinavian royals (in other country Fred wouldn't have gotten away with so many things, and all the blondes we don't know), but the Norwegian royals have the easiest ride of them all. Haakon could have had hundreds of affairs with much less discretion than Fred, and we wouldn't know a thing because most of their private time they're left to their own devices (Not that I'm saying he has had affairs)
In any case it's odd that the husband is partying in another continent while the wife is going to undergo a mysterious surgery (where else would the press allow this uninformative press release from their royals?) and needs to take sick leave.
