Our local school made one of my daughters take speech therapy for about 3 years because they said she didn't say her "R" sound correctly. I hardly ever noticed it. I kept telling the speech person that if she was from New Hampshire it wouldn' have been a problem. Up there everybody said it that way. I grew up in Kansas & had relatives from Montana tell us we had a southern accent.
You know the diffewrence between a northern girl & a southern girl?
A northern girl says "You can."
A southern girl says "Y'all can."
