I'm not from the UK/EU, but I would have voted to stay. From what I know of the situation, it seems like the pros of staying outweigh the pros of leaving. But it seems that the majority of the UK disagrees. I wish you guys luck.
Also, poor Scotland. I'm friends with a lot of Scottish people and the majority of them basically say f*** you to the UK and want out and back in to the EU.
That depends. Nicola Sturgeon is looking for a way to block the Brexit altogether, but if that doesn't work out then there will likely be a second referendum about Scotland's independence.
