My kids and grands get so angry at me when I correct them ... but like the article says, "As standards decline, civilization declines." Maybe this makes me a stickler, or a prude ... but this is the way I operate. I can speak slang and I keep up with the meanings of all the new youth and tech lingo. That doesn't mean I have to say (this on top of my list of phrases that make me cringe), "I'm done!"

A time and a place,okay in the pub not at an interview.

I don't think I'd want to try correcting someone's grammar after they've had a few drinks. I think it's useless to correct an adults grammar, they're aleady set in their speech pattern. But a child just starting school is fair game as is a young person just finishing school.

I think it's most important to adapt a way to correct somebody's grammar, based on a) who they are; b) where you are; c) when you deem it right. Absolutely nothing annoys me more than someone repeatedly making a grammatical mistake. It's probably got to do with the fact that every time someone says "reply back", the voice in my head goes "it's just reply and not 'reply back' you ass". That's just an example. Where I come from (India) it is so perfectly normal to say "What you had?" for "What did you have (for lunch/dinner)?" Absolutely annoying.
