Hmm this discussion feels like a trap for the Direct Dutchie (I'm not even that direct by Dutch standards) to wade into and make enemies. Btw this site is good for bypassing paywalls, I use it all the time for the NY times recipes which used to be freely available.
I wouldn't suggest being more like me in the UK Flo, considering I think my cultural directness averages at least one (near) xenophobic incident directed at me whenever I'm there. Granted I've always been able to detect British passive aggressive sub speak (I don't really know where/how) and probably suspect to perceive some of it when it isn't always there as a result so that probably doesn't help either.
I would say it isn't an English language thing, it's very specific to the UK (I have different issues with Americans, they always think I'm hilarious 
) and it seems tied into the class system. Shangpie's list is very much one for the (highly) educated classes IME, I don't imagine Alan Sugar goes round politely saying something is interesting when it's not and in certain sectors of society calling a spade is a spade is the preference. I also get the sense those that have grown up/working in the UK forces have a separate language and coded words as well that are difficult to understand as an outsider. As a foreigner living in the UK you're probably better off living in ignorance and thinking everyone is just being really nice to you. A Kenyan friend of my mother always echoed what quirky mentioned about being polite to your face but actually being really rude, and often a lot happens behind your back, she loved the directness of the Dutch because she said it may not always be pleasant but at least it's honest and you know where you stood with someone. There's sure to be some middle ground though (but if we're no longer to use 'ducks in a row' per that article I do worry that MN will implode).
The French do it too, to a point, but it's opposite world where things are understated, pas mal is really really good, etc.
In other catch up, quirky hope it works out for your DD and that other DD recovers quickly.
Red I suspect you saw a variation of a hakama trouser, they're a proper Japanese wardrobe staple since forever. My favourite are the ones worn by shrine maidens (how apt on this thread), not really visible in these pics but the original versions have openings at the side so a short kimono can be worn underneath. I've seen a lot of Japanese brands popping up lately, granted it's in small boutiques in France and Belgium, especially the Nico Nicholson and Nicholson brand, not related to Studio Nicholson but there's a bit of aesthetic overlap.
