When I first heard about Brexit, I was literally thinking "what were they thinking". I'm still not entirely sure if it's a good or bad thing for England but that's what they voted for.
Leading up to the referendum, the mean vindictive part of me had a "good riddance" attitude at the thought of their leaving, since Cameron had basically gone over there and said "either you put in place these 'reforms' that give us special treatment or we're off". But when I actually heard the result that morning it was just a complete "oh crumbs" moment.
Within hours I'd come up with plenty of Fawlty Towers and Fools and Horses jokes though.
