But y'all should know that we Southerners - when conversing with family, friends and business associates from the Midwest and North make an effort to say "you guys".
When it is a formal/semi-formal business discussion it is rare (and perhaps a slip) if we say y'all.
Sure, we slip back into our natural accent and terms when we relax. However, we observe that more Southerners are saying "guys" - so perhaps there is a blend.
Reminder: We practically NEVER say "you-all" (except older people.) Y'all - when spoken to an individual - is NEVER meant as a singular term. Someone else (family, group, etc. is included.) And one of the harshest sounds to a Southerner is the dropping of "g" from the "ing" in movies/plays.
It immediately becomes apparent that the actor/actress is not from the South, nor is the director. Southerners don't say "Anythin".
To conclude on "Y'all"; it does have a warmth and informality to it. And warmth, informality and instant superficial friendship is what Southerners are know for. :o)
Now can we move on to discussions of why Bostonians can't pronounce "Peabody" correctly? :o)
tell your mom and them I said hey...
