Yorkie, you are mean! LOL. XD Well, at least I'm not feeling nervous.
Well, one thing you know for sure is that none of the boys are from North London because if they were, it's take them an hour and a half or more to get to Norbury. I would know, because I'm FROM North London, yay! No, it actually sucks.

They are all from South London and the area OUTSIDE of London that is near South London. In fact, the parts of South London most of them are from can't even be reached by Tube! Not easy to travel there at all, even if you live within the area! Buses and railways are mainly used to get there.
