Read this comment on reddit and thought it was interesting:
My wife and I arrived early morning in Manchester, UK. We came because I had to write an economic history paper and the University there had given me permission to spend the week utilizing its resources. By 09:45 sorted out permission from the library and worked out where the collections I needed were. Spent apx another hour looking for accommodation, bumped into an aussie who ran a pub and said we were looking for a week's digs. Got that sorted. By say around 11 we were walking back into the city centre. My wife grabbed my arm and said, 'We have to go! We need to leave!" Of course one queries that and I objected fairly sternly saying we have just got ourselves organized etc etc. Nonetheless we went back to the pub picked up our packs and she dragged me to the bus depot. I was damn ****ty at this irrational behaviour. Never in 8 yrs of marriage had she done anything like this or behaved in this manner. We went to the main bus depot paid for the first bus out - which went to Edinburgh and off we went. My wife visibly relaxed on the bus. I backed off my aggression, accepted this stupidity and inconvenience and wondered what on earth had got hold of her.
20 mins into the bus trip the driver made an announcement. The IRA have set off a very large bomb in Manchester central. It devastated the entire city centre. They did apparently give a warning to authorities and the centre was just cordoned off in time. We didn't see that though.
I asked her how did you know? And all I have ever got is that " I felt there was something wrong and we had to go."
