Occasionally I like to imagine myself moving to the UK after I graduate, almost entirely because it would give me an excuse to start talking in a British accent all the time. Yeah, I'm sure everyone within earshot would immediately be able to tell it's a fake, but given the combination of constant practice and constant exposure, the prospect of eventually acquiring it is enough for the idea to remain tempting (in the same way abandoning the stresses of modern life to go live in the woods is sometimes tempting - e.g. not something you'll ever actually do).
