1/ No.
2/ Yes
3/ No
4/ No. I speak with a fairly broad working class South-West London accent.
5/ Given the number of children born out-of-wedlock in the last 40 yrs, double-barreled surnames are quite common among working class people, you eejit.
6/ I complain about gentrification. I'm a tenant on a council estate. I complain about it because it forces working class families out of traditionally working class areas. Brixton, for example, is being whitewashed, & everything that makes it such a great place is fading away because of...gentrification.
Stick your generalisations up your arse, boy.
