In England,we are often urged to talk proper,like what the Queen do.
But seriously ....we all need to have,and to learn, some basic rules of grammar in our own language,otherwise how could we learn anyone else's tongue ??

Meanwhile :
            "They were goin' down the river,
                Sittin' in the stern ;
             She were 'oldin' 'is'n
                   An' 'e were 'oldin' 'er'n "

As to trying to get people to understand the correct usage of Sink / Sunk....Ring /Rang.....Hang / Hung etc,and,worst of all, Fewer / Less ( drives me nuts !)   ... I give up !! And nobody I know writes
'bus (Omnibus)....'phone (Telephone) and 'plane (Aeroplane) as do I !! But of course, they damn well SHOULD !! Sigh !
