Re: Im going to try and be open minded but I do have my reservations.
It really just depends on the person. My dad isn’t educated past A levels and came here when he was 18. He has an accent (difficult to place now) but his command of English is great. It probably has a lot to do with the fact that my mum came to the UK when she was 5 and therefore speaks English like a native and also that my parents associated with all kinds of people. My dad loved watching all the TV shows, like Yes Minister, Rising Damp etc etc. We lived in Bournemouth for a few years in the 80’s and just to give you an idea of what that was like, I was the only non-white child in the primary school!
Now if this guy has chosen to most of his time with fellow Pakistani’s and conversing and joking in Urdu/Punjabi, then he make not have progressed in this respect very much.
