Most southerners drop parts of their words. I do it. My family back home does it. And even Reagan, who is one part southern, does it. I posted a while back about how she would drop the "a" on adult....making it sound more like "dolt" (which is, admittedly, sometimes correct!)
The other day I realized I needed to pay much more attention to our speech patterns as this was the conversation that occurred as we were leaving the park:
Mommy: What way do we go now Reagan?
Reagan: To the right!
Mommy: Very good! I'm so proud of you for learning all this!
Reagan: Mommy, I can drive now.
Mommy: Oh really?
Reagan: Yep, I can drive because now I know all my 'irections! (And if you read that properly without the "d" sound...you'll realize EXACTLY what she said!)
