Dog: was not referring to your post but thanks for the info. I used to use the generic "one" in speech and written word rather than "you" and still think it is more correct but, idiomatically, the generic you is now very much in use. I get laughed at if I use "one" instead of "you" now .........
However people should never say "youse" or "alls" and if they persist with it should be horsewhipped and press-ganged on to my next ship bound for elocution lessons in the Pacific (inbetween Pirating episodes)
Capt Jack Sparrow.
PS. Let's not start on the use of "who" and "whom" and the possesive apostrophe!
