living in a council house (a lot luckier than many who deserve same) and writing proper english, or even understanding how to do so, are nothing to do with one another.

would be just as happy to say it to your face ...... but why that log of wood on your shoulder? ...... "aren't" by the way, and as it happens i spent the first 15 years of my working life in Brick Lane
