Perhaps one of the reasons Brexit is so discombobulating is that the UK has rarely had to cope with natural disasters. No earthquakes, volcanoes, or tidal waves. No hurricanes, or certainly none even remotely approaching the fury of those that regularly ravage the Atlantic and Pacific basins.
So, aside from the generation that lived through WW2, none of us have experience of overnight upheaval, of the upending of "normal". That makes the warnings surrounding Brexit seem surreal, or false, depending on your politics - but never immediate, never truly visceral.
Brexit is likely to be equally unreal for most of our politicians, even with just over 60 days to go. Few will have woken in a cold sweat, or felt their gut knot as the reality of our dire situation hits home.
Until Brexit gets real, they will continue to dodge and dither and prevaricate.
