London is beautiful, isn't it?

Not really. Maybe in the more dear places such as Piccadilly Circus or Paddington or Chelsea, things are more expensive, but main stores are quite cheap, even compared to other cities in England (I keep an eye out for prices and I noticed that stuff were cheaper in London than in a city more North).
Also, it's not really filled with 'posh' twats, it's actually full of common people, Idoubt you'd find a posh person at first sight.

Everyday stuff is more expensive in London

No it's not.

I saw a woman sitting at the bus stop pissing, when I was 11. It was so ew.

But I still love it ♥

That's the point

Yaassss
