Impossible would be a better description. If I click on the link I get a page that disappears before I can see what's on it, followed by a blank Google+ screen. I'm not going to waste any more time on this rubbish.
Sorry, none of the above.
Obvious clue, on the Western Line and someone has been VERY close.
By the way, sorry about my attitude. I apologise deeply and hopefully, you won't see anything of that sort from me again.
