It turns out that said man was a Bulgarian immigrant. I asked him how long he had been here, he replied, "one month". His English wasn't terribly good, as you can expect, but we managed to hold a brief conversation.
I doubt he was homeless in Bulgaria, but he maintained he was here, in Britain, 'looking for work'. Good luck to him. I asked him if he was a Christian, he said that he was. You could tell he wasn't your average Brighton homeless man because he was sober. I wished him happy Easter and went on my way. Welcome to the United Kingdom, where all your dreams come true. I didn't have the heart to tell him that according to official Government policy he only has two months left before being packed back to Bulgaria, but then I guess that what with having no address, he might not get the letter from David Cameron telling him to go home in the absence of employment or the letter that welcomed him to the UK.
Perhaps David Cameron is a Christian after all. He seems awfully keen on inviting orthodox Christians from Bulgaria and Romania here en mass, as well as Polish Catholics here en mass. Another 40 years of that and this country will be Christian once more.
