A few Romanians think it's magnificent of Britain to decide to leave the EU, but most are displeased, many very angry, because the only reason they can imagine why we are leaving is because of dislike of Eastern European immigrants. This hurts them all the more since the UK has so many non-white citizens.
They think we are even more arrogant then they already believed (which was very). They mostly don't believe that we simply want to make our own laws.
Among the politicians there is unhappiness about losing an ally at Brussels and incomprehension that we are leaving just because of a referendum. Referendum results in Romania are often simply ignored. Or even rigged. The result of the EU referendum here was widely believed to be rigged (so that the minimum turnout threshold was reached).
And Romanian politicians do not understand why David Cameron called a referendum just because he won an election on a promise to do so.
It all makes you proud to be British.
They also mostly think we won't really leave. And the lesson I draw is that no-one ever understands another country's politics.
