I reckon we have a beautiful range of language on this island, CD.
I for one refuse to believe that language barriers started with the 'influx' of Polish people, in fact immigration at all!
The funniest thing I have ever seen was at Mr Pippas last Christmas do at work. There he was with two of his best workmates ~ one a Geordie and the other a Scot. Mr Pippa has a typical East Surrey accent (not posh, not slovenly).
After each sentence spoken, one or the other was saying ''eh??'' it was almost like United Nations..
