Re: Its the old
"Welcome to London"?
Shurely some mistake. The UK (well, (some of) England, mostly) doesn't seem to do "welcome" these days.
"Go away, you you horrible funny-speaking and/or funny-coloured people" would very sadly be a more appropriate sign these days.
The rest of us weep that our country seems to have been taken over by xenophobes and racists, and we are quite nice people, honest. We'll admit that we're a bit puzzled why you decide to move to our crowded, damp, and rather ramshackle country, but, as long as you're here legitimately and honestly, we do like that you have chosen to do so (and we would hope for the same if we chose to emigrate elsewhere). Any country where everyone was near-enough exactly the same would be horrible.
