Proper English ain't nowhere to be found

It's almost everyday one hears incorrect english, but do we anything about it? Maybe at the risk of sounding pedantic and cranky we desist. Well, think of this next time you hear a kid speaking like that. Do him/her a favor (favour) and gently correct them. Thankfully I am not alone in this quest --> An Article in AZ Central
